SecuringAIAgents:ClaudeDesktop&DescopeEnterpriseAuth

📋 At a Glance

Here’s the TL;DR:

• Difficulty: Intermediate (I wouldn't call this beginner stuff, but it's not rocket science either.)
• Time required: 45-75 minutes (if you don't hit any of the usual Python environment gotchas, that is.)
• Prerequisites:
  • Basic understanding of Python and web application concepts (APIs, HTTP requests). (If you’re here, you probably know this, but a reminder never hurts.)
  • A Descope account (yeah, free tier works for dev, obviously).
  • An Anthropic API key for Claude (if you're hitting the API directly, otherwise, good luck).
  • A functional AI agent (a Python script is fine) ready to run on your desktop.
  • Python 3.9+ installed with pip. (Seriously, if you're still on 3.8, upgrade.)
• Works on: macOS, Windows, Linux (for your local agent and Python stuff); Descope itself is cloud-based, so that bit doesn't really care what OS you're on.

How Do I Architect Enterprise Authentication for a Desktop AI Agent?

Alright, let's talk about building enterprise authentication for a desktop AI agent. This isn't just slapping a login form on a website. You've got a local agent, usually running on some user's machine, and you need to ensure only authenticated, authorized people can make it do things. My approach? We hook into a cloud-based Identity Provider (IdP) like Descope. Descope handles the messy stuff – user sessions, access policies. Our local agent? It just validates tokens and authorizes actions. This keeps the complex security bits out of our agent's core AI logic, letting it focus on, well, AI tasks, while still locking down who can even talk to it. The agent kicks off the auth flow, gets tokens back, and then double-checks those tokens with Descope before even thinking about doing anything sensitive.

Throwing enterprise-grade auth into a desktop AI agent, especially if it's doing something critical like payments, is always a headache. The real challenge with desktop apps is managing user sessions and credentials securely without a constant server connection. Descope, to its credit, tackles this by being an external auth service that our desktop apps can poke via their SDKs and APIs.

Here’s how I typically break down the core architecture:

1. Descope Project: This is where all the auth flows (SSO, passwordless, email/password – pick your poison) and user management live. It’s your auth backend.
2. AI Agent (Python app): Running right on the user's desktop. Its job is to hit Descope for auth, snag session tokens, and then use those tokens to prove who the user is and what they’re allowed to do before executing anything.
3. Claude Integration: Our agent talks to the Claude API (or whatever local Claude setup you've got). Descope's job isn't to secure Claude's API directly. It's to secure who can tell our agent to talk to Claude. Big difference.

Just so we’re clear: I’m assuming your "Claude Desktop" agent is a Python app running locally and hitting the Anthropic Claude API. No fancy stuff for now.

How Do I Set Up a Descope Project for AI Agent Authentication?

Alright, time to get our hands dirty setting up Descope. This means signing up, making a project, and defining the bare minimum for auth flows – email/password or passwordless, whatever you prefer. This is your initial security layer. You'll walk away with a Project ID and Management Key. Remember those; they're vital for actually connecting your agent.

Think of this as building the backend for your authentication system. This is where you decide how people log in and what apps they get to touch.

Step 1: Create a Descope Account and Project

What: Get your Descope account and project spun up. No way around it. Why: This is ground zero. Everything else hinges on having a dedicated Descope environment for your app. How:

1. Hit https://www.descope.com.
2. Click "Start Free" or "Sign Up". You know the drill.
3. Once you're in, they'll ask for a new project. Call it something sensible, like ClaudeAgentAuth.
4. You’ll land in the Descope Console for your shiny new project. Verify:

✅ Look for your new project dashboard. Seriously, don't miss this: grab your Project ID (Project Settings -> General) and your Management Key (Project Settings -> Project Access Keys -> New Key). Without these, you're dead in the water for integrating with your agent.

Step 2: Configure an Authentication Application

What: We need an 'application' within your Descope project. Think of it as defining who's actually going to use this auth service. Why: This lets you control different auth flows and redirect URLs for different clients. Crucial for sanity. How:

1. In the Descope Console, hit Applications in the sidebar.
2. Click New Application.
3. Name it. Something like Claude Desktop Agent.
4. For Application Type, Web Application or SPA (Single Page Application) is usually closest to what a desktop app does for web-based auth. Pick one.
5. Now, Redirect URLs. This is important. For a local desktop agent, you're usually looking at a loopback address or a custom scheme. http://localhost:3000 or http://127.0.0.1:3000 are typical for local dev. If you're going fancy with a custom URI scheme (like myagent://auth/callback), add that too.

   ⚠️ Warning: For production, I'd strongly recommend a custom URI scheme and always robust state parameter validation. This blocks redirect attacks. For basic local dev, localhost usually flies, but don't get complacent.

6. Click Create Application. Verify:

✅ Your new app should show up in the Applications list. Double-check those Redirect URLs. Seriously, a mismatch here can cost you hours debugging a 'something went wrong' page.

Step 3: Define Authentication Flows

What: Decide how users will actually log in or sign up for your AI agent. Why: Descope gives you ready-made flows – Magic Link, Email/Password, Google SSO. This saves you a ton of frontend work and complex logic. How:

1. In the Descope Console, hit Authentication Flows.
2. Grab an existing flow (like Email and Password) or roll your own.
3. Tweak it if you need, but for a quick start, the defaults for Email and Password or Magic Link are usually fine.
4. Make sure this flow is tied to your Claude Desktop Agent application. Verify:

✅ You should see your chosen flow active. Hit Preview in the Descope Console to make sure the login UI actually loads. It's a quick sanity check.

How Do I Integrate Descope Authentication into My Python AI Agent?

Alright, now for the real integration – getting Descope into your Python AI agent. This means installing their Python SDK, firing it up with your Project ID, and writing the actual code to kick off authentication and validate user sessions. Your agent will basically tell the user, 'Hey, go log in on this webpage,' then grab the session token Descope spits out, and use its SDK to verify everything. This is where your local agent finally talks to your Descope backend, putting those auth flows to work.

Step 1: Install the Descope Python SDK

What: Get the Descope Python SDK into your agent's environment. No magic here. Why: It's the easiest way to talk to the Descope API – auth, session validation, user management. Saves you from reinventing the wheel. How:

1. Fire up your terminal.
2. Go to your AI agent's project directory.
3. Seriously, use a virtual environment. I've spent too many hours debugging dependency conflicts. Do it:

   # What: Create a virtual environment.
   # Why: Keep your project dependencies isolated. Global Python packages are a mess waiting to happen.
   # How:
   python3 -m venv venv
   # Verify: You should see a 'venv' directory. If not, something's off.
   
   # What: Activate that environment.
   # Why: So you're actually installing into and running from your isolated sandbox, not messing with your system Python.
   # How (macOS/Linux):
   source venv/bin/activate
   # How (Windows PowerShell):
   .\venv\Scripts\Activate.ps1
   # How (Windows Command Prompt):
   venv\Scripts\activate.bat
   # Verify: Your terminal prompt should now have '(venv)' at the start. If not, it didn't activate.
   

4. Now install the Descope SDK and python-dotenv (you'll want that for credentials, trust me):

   # What: Install the Descope SDK and python-dotenv.
   # Why: SDK for Descope's API; dotenv for loading environment variables safely.
   # How:
   pip install descope python-dotenv
   # Verify: You should see "Successfully installed..." for both. If you get errors, check your venv activation.
   

Verify:

✅ Run pip list inside your activated virtual environment. Make sure descope and python-dotenv are there. If they're not, you probably installed them globally or your venv isn't active.

Step 2: Securely Store Descope Credentials

What: Your Descope Project ID and Management Key? Lock them down as environment variables. Why: Seriously, hardcoding secrets is how you end up on the next major data breach headline. Environment variables keep them out of your code and make managing different environments (dev, staging, prod) a hell of a lot easier. How:

1. In your agent's project root, create a file called .env.
2. Dump your Descope Project ID and Management Key in there. Swap YOUR_DESCOPE_PROJECT_ID and YOUR_DESCOPE_MANAGEMENT_KEY with the actual values you noted earlier.

   # .env
   DESCOPE_PROJECT_ID="YOUR_DESCOPE_PROJECT_ID"
   DESCOPE_MANAGEMENT_KEY="YOUR_DESCOPE_MANAGEMENT_KEY"
   ANTHROPIC_API_KEY="YOUR_ANTHROPIC_API_KEY" # Only if you're hitting Claude directly
   

   ⚠️ Warning: Listen up. DO NOT COMMIT YOUR .env FILE TO GIT. Add /.env to your .gitignore right now. This isn't optional.

3. Now, in your Python script, pull those variables in using python-dotenv:

   # main.py or wherever your agent starts up
   from dotenv import load_dotenv
   import os
   
   load_dotenv() # Load those .env variables
   
   DESCOPE_PROJECT_ID = os.getenv("DESCOPE_PROJECT_ID")
   DESCOPE_MANAGEMENT_KEY = os.getenv("DESCOPE_MANAGEMENT_KEY")
   ANTHROPIC_API_KEY = os.getenv("ANTHROPIC_API_KEY")
   
   if not DESCOPE_PROJECT_ID or not DESCOPE_MANAGEMENT_KEY:
       # If these aren't loaded, you've messed up. Stop the presses.
       raise ValueError("Descope Project ID or Management Key missing from environment variables. Check your .env file and .gitignore.")
   

Verify:

✅ Write a quick throwaway script with load_dotenv() and os.getenv(). print() the variables. See if they're there. Then delete the print statements. You don't want secrets in your logs.

Step 3: Implement Descope Authentication Flow in Your Agent

What: Time to write the actual Python code. This means initiating the login, catching the redirect, and verifying the Descope session. Why: This is the engine of your authentication. It's how users prove who they are and how your agent gets the token it needs to operate securely. How:

1. Initialize the Descope SDK and set up a basic local server to catch redirects. This is a common pattern for desktop apps. We spin up a tiny HTTP server on localhost that waits for Descope to redirect the user back with an authentication code. I've debugged enough of these to know that getting the redirect URL exactly right is usually the first hurdle.

   # descope_auth.py (or bake this right into your main agent script)
   import descope
   import os
   import webbrowser
   from http.server import BaseHTTPRequestHandler, HTTPServer
   from urllib.parse import urlparse, parse_qs
   import threading
   import time
   
   # We assume DESCOPE_PROJECT_ID is loaded from .env, because you followed Step 2, right?
   dclient = descope.DescopeClient(project_id=os.getenv("DESCOPE_PROJECT_ID"))
   
   REDIRECT_PORT = 3000 # This *must* match one of the Redirect URLs you set in Descope
   REDIRECT_URL = f"http://localhost:{REDIRECT_PORT}"
   
   class AuthCallbackHandler(BaseHTTPRequestHandler):
       """
       A simple HTTP server handler to catch the OAuth redirect callback.
       This is basically just waiting for Descope to send us the auth code.
       """
       def do_GET(self):
           parsed_url = urlparse(self.path)
           query_params = parse_qs(parsed_url.query)
   
           if parsed_url.path == "/auth/callback": # Ensure this path matches your Descope redirect config
               code = query_params.get("code", [None])[0]
               if code:
                   self.send_response(200)
                   self.send_header("Content-type", "text/html")
                   self.end_headers()
                   self.wfile.write(b"<h1>Authentication successful! You can close this window.</h1>")
                   self.server.auth_code = code # Stash the code away for the main thread
               else:
                   self.send_response(400)
                   self.send_header("Content-type", "text/html")
                   self.end_headers()
                   self.wfile.write(b"<h1>Authentication failed: No code received.</h1>")
           else:
               self.send_response(404)

   def get_auth_code_from_redirect():
       """

       if user_session:
           print(f"User '{user_session.user.login_id}' is now authenticated. Your AI agent can get to work.")
           # This is where your actual Claude AI agent logic would start.
           # For example:

       else:
           print("Authentication failed entirely. Agent is useless.")
   

Verify:

✅ Run your Python script (python descope_auth.py). It should pop open a browser to the Descope login page. Log in with a user you set up earlier. If all goes well, the browser redirects, and your script should confirm 'Authentication successful' and spit out some session details. If it hangs or errors, check your REDIRECT_PORT and flow_id first.

Step 4: Secure AI Agent Actions with Session Validation

What: This is where you actually lock down your agent. Don't let it do anything sensitive unless a valid Descope session is active. Why: Access control. Plain and simple. Only authenticated users get to trigger those critical AI agent functions – like, say, processing a payment or deleting all your data. (Don't let it delete all your data.) How:

1. Everywhere your agent performs a sensitive operation, add a gate. Check for that validated session object.
2. Pass the validated_session (or at least the session_token) down to any function that needs to confirm user identity or permissions.

   # Example of integrating session validation directly into your agent's core
   import anthropic
   # Again, assume ANTHROPIC_API_KEY is loaded from .env. If not, see Step 2.
   
   class ClaudePaymentAgent:
       def __init__(self, api_key: str):

       print("\n--- Initiating a sensitive action (e.g., payment) ---")
       if agent.process_payment(user_id, 100.00, "Monthly cloud subscription"):
           print("Agent successfully processed payment due to valid user session.")
       else:
           print("Agent failed to process payment.")
   
       # We'll cover roles in the next section, but here's a sneak peek:
       if "admin" in user_session.user.roles:
           print(f"Heads up, {user_id} is an admin. They can do anything.")
       else:
           print(f"User {user_id} has standard privileges. Keep them away from the delete button.")
   
   # How you'd call this from your main script:
   # if __name__ == "__main__":
   #     load_dotenv()
   #     user_session = authenticate_user()
   #     if user_session:
   #         run_agent(user_session, ANTHROPIC_API_KEY)
   #     else:
   #         print("Authentication failed entirely. Agent is useless.")
   

Verify:

✅ Run your agent. It must prompt you for Descope login first. Once you're in, run_agent should fire, and you should see those process_payment messages. Try to bypass auth (e.g., by commenting out authenticate_user() and running run_agent(None, ANTHROPIC_API_KEY) – you should get an 'ACCESS DENIED' message).

When Claude Desktop + Descope Is NOT the Right Choice

Look, Descope sells itself on simplifying auth for AI agents, and it mostly does. But let's be real: it's not a silver bullet. Sometimes, it’s just not the right tool for the job. You need to know when to walk away, or you'll end up over-engineering or introducing unnecessary dependencies. Don't fall for the hype if your situation doesn't fit.

1. Truly Offline Agents: If your AI agent is stuck in an air-gapped environment or genuinely doesn’t need internet connectivity, Descope is useless. It’s cloud-based. Full stop. You're better off with local credential stores or simple password protection – with all the inherent security compromises, obviously.
2. Existing, Heavyweight Enterprise IdPs: Large corporations already have their Okta, Azure AD, or Ping Identity setups, often with deep SAML/OIDC integrations. While Descope can connect to these, sometimes adding another layer just creates more complexity, compliance headaches, or vendor lock-in. If your existing IdP does the job and you don't need Descope's specific bells and whistles, just integrate directly. Less moving parts, less to break.
3. Minimal Security, Internal Tools: For a small, trusted team using a non-sensitive internal tool, Descope might be overkill. A simple API key, a shared secret, or even just OS-level user authentication (if you trust your users not to share their desktop logins) could suffice. Save yourself the complexity and cost.
4. Budget Constraints, Even for 'Enterprise': Descope has a free tier, sure, but those 'enterprise' features – huge user counts, advanced SSO, compliance certs, dedicated support – cost money. If your budget is tighter than a drum and your 'enterprise' needs are mostly just basic auth for a large user base, then you'll need to look at open-source options or building out direct OAuth/OIDC yourself. Be prepared for a lot more development effort, though.
5. Really, Really Custom Auth Flows: If your AI agent has some truly bizarre, non-standard authentication logic that Descope's pre-built components simply can't handle, and tweaking Descope becomes a nightmare, then a bespoke auth system might offer more flexibility. This is rare, Descope is quite configurable, but there are always edge cases where you hit the wall.
6. Milliseconds Matter (Performance-Critical): Any external authentication service adds network latency. If your agent absolutely needs sub-millisecond authentication responses and every single millisecond counts, you might look at a purely local token validation mechanism (after an initial login) or a highly optimized in-house solution. But be warned: the complexity here escalates exponentially, and you're probably sacrificing other benefits.

For most modern AI agents that need secure, scalable, and user-friendly authentication, Descope is a solid choice. But being a good engineer means knowing when to question the default and look for alternatives.

How Do I Add Role-Based Access Control (RBAC) to My AI Agent with Descope?

Implementing Role-Based Access Control (RBAC) for your AI agent with Descope means two things: first, you define roles and permissions in Descope and assign them to users. Second, your agent pulls those roles from the validated session and checks them before letting anyone do anything sensitive. This is how you ensure only users with the right clearances can actually perform certain actions. For enterprise applications, RBAC isn't optional; it's how you carve out different access levels – admin, editor, viewer, payment_processor, whatever you need.

Step 1: Define Roles and Assign to Users in Descope

What: Create custom roles in Descope and give them to your test users. Why: This builds the permission framework on the Descope side, which your AI agent will rely on. How:

1. In the Descope Console, go to Users.
2. Pick an existing user or create a new one for testing.
3. In the user's details, scroll down to Roles.
4. Click Add Role and type a role name – payment_processor, admin, analyst – whatever makes sense for your app.
5. Assign the roles you want to your test user. Verify:

✅ The user's Descope profile should now show their assigned roles. Make at least two users with different roles (e.g., one with payment_processor, one without) so you can actually test the RBAC.

Step 2: Retrieve and Utilize Roles in Your AI Agent

What: Modify your AI agent to read those user roles from the Descope session and then, based on those roles, decide what the user is allowed to do. Why: This is how you get granular access control. Without it, everyone is either admin or a guest. Not great for enterprise. How:

1. Once dclient.validate_session() returns that validated_session object, it's got all the user info, including their roles.
2. Access validated_session.user.roles – it's a list. Use it.
3. Now, just write your if statements. Simple, conditional logic to gate sensitive functions.

   # In your run_agent function, or wherever you handle operations:
   def run_agent_with_rbac(user_session, claude_api_key):
       if not user_session or not user_session.is_valid:
           print("ACCESS DENIED: No valid session. Please authenticate first.")
           return
   
       user_id = user_session.user.login_id
       user_roles = user_session.user.roles # Get those roles!
       print(f"User {user_id} is authenticated with roles: {', '.join(user_roles)}. Agent is now active.")
   
       agent = ClaudePaymentAgent(claude_api_key)
   
       print("\n--- Checking role-based access for payment processing ---")
       # Example: Only allow 'payment_processor' role to process payments
       if "payment_processor" in user_roles:
           print(f"User {user_id} HAS 'payment_processor' role. Allowing payment.")
           if agent.process_payment(user_id, 250.00, "Enterprise license fee"):
               print("Payment successfully processed by agent (RBAC enforced).")
           else:
               print("Payment processing failed (even with role, something else went wrong).")
       else:
           print(f"User {user_id} does NOT have 'payment_processor' role. Payment processing denied.")
   
       print("\n--- Checking role-based access for administrative actions ---")
       # Example: Admin-only functions
       if "admin" in user_roles:
           print(f"User {user_id} HAS 'admin' role. Unlocking administrative functions.")
           # Your admin-specific logic goes here. Be careful.
       else:
           print(f"User {user_id} does NOT have 'admin' role. Administrative functions blocked.")
   
   # Again, how you'd hook this up in your main script:
   # if __name__ == "__main__":
   #     load_dotenv()
   #     user_session = authenticate_user()
   #     if user_session:
   #         run_agent_with_rbac(user_session, ANTHROPIC_API_KEY)
   #     else:
   #         print("Authentication failed. No access for the AI agent.")
   

Verify:

✅ Run your agent multiple times. Log in with a user who has payment_processor and verify they can make payments. Then, log in with a user who doesn't have it and confirm they're blocked. Do the same for admin or any other roles. This isn't theoretical; you need to see it work.

What Are the Key Security Considerations for a Desktop AI Agent?

Securing a desktop AI agent? It's a whole different beast than a server app. Your agent is out there in the wild, on some user's machine, not in your perfectly controlled data center. This means you have to protect credentials, manage sessions like a hawk, validate every input, and use secure comms. Ignore this, and you're just asking for an unauthorized access or data breach.

Desktop environments introduce challenges that'll make you pull your hair out if you're not careful.

1. API Key Management:

   • What: I'm saying it again: NEVER hardcode API keys. Not for Anthropic, not for Descope, not for your payment gateway. Ever.
   • Why: Your code gets shared, it gets compromised. Hardcoded keys are freebies for attackers.
   • How: Use .env with python-dotenv for local dev. For actual deployments, look at OS-specific secure storage (macOS Keychain, Windows Credential Manager) or, for proper teams, something like HashiCorp Vault.
   • Verify: Check your repo. Are keys actually loaded at runtime and not sitting in plain text in your source? Good.

2. Redirect URL Security:

   • What: Those OAuth/OIDC redirect URLs? Configure them with extreme prejudice.
   • Why: A misconfigured redirect URL is a classic open redirect vulnerability. Attackers will snatch auth codes and tokens faster than you can blink.
   • How: http://localhost:<port> or a custom URI scheme (myapp://auth/callback) for desktop. Always validate the state parameter on callback to prevent CSRF. Descope's SDK helps, but if you roll your own, you own the risk.
   • Verify: Try to mess with the redirect URL or the state parameter during a test login. Does it fail gracefully and securely? Or does it expose something?

3. Session Management:

   • What: Descope session tokens (sessionToken, refreshToken) need to be handled with care.
   • Why: Stale or stolen tokens mean unauthorized access. Period.
   • How: Keep session tokens in memory if you can. If you must store on disk, encrypt them heavily (and then question your life choices). Implement refresh token rotation. Your agent must regularly validate the session with Descope. And always, always log users out explicitly.
   • Verify: Simulate session expiry. Does your agent ask to re-authenticate or use a refresh token properly? If it just crashes, that's a bug.

4. Input Validation and Sanitization:

   • What: Every single user input to your AI agent? Validate and sanitize it.
   • Why: Prompt injection against your LLM, command injection if your agent runs system commands. Bad news.
   • How: Use libraries to clean text before it hits the LLM. Strict schema validation for structured inputs.
   • Verify: Throw everything you've got at your agent: SQL injections, shell commands, nasty prompt injections. Does it choke safely or execute something unintended?

5. Least Privilege Principle:

   • What: Give your AI agent and its processes only the absolute minimum permissions they need.
   • Why: If it gets compromised, you want the smallest possible blast radius.
   • How: Run the agent with a user account that has restricted file system access. Ensure its code only calls necessary APIs and avoids unnecessary system commands. Use Descope's RBAC to limit what authenticated users can do.
   • Verify: Audit your agent's dependencies and external calls. Is every system-level operation truly necessary? Is it locked down?

6. Error Handling and Logging:

   • What: Implement robust error handling and secure logging.
   • Why: Stop info leaks and actually diagnose issues, not just guess.
   • How: Catch exceptions gracefully. Never, ever log sensitive info (raw tokens, API keys, full error stack traces with juicy data) where anyone can see it. Ensure logs are locked down to authorized eyes only.
   • Verify: Force various error conditions (bad API keys, network drops). Check your logs. Is anything sensitive showing up? Fix it.

Address these security considerations diligently. It's not glamorous, but it's how you build a robust and trustworthy Claude Desktop AI agent that won't become a security nightmare.

#Frequently Asked Questions

Can I use Descope's free tier for enterprise authentication? You can start with Descope's free tier, sure. It gives you a decent base. But 'true enterprise' usually means you'll eventually need custom SAML/OIDC, way more users, and dedicated support – which are, surprise, in the paid plans. So, before you commit, honestly assess your organization's scale, compliance needs, and how it'll integrate with your existing IdPs.

How does Descope actually make my Claude AI agent more secure? Descope takes the heavy lifting out of authentication. It centralizes tricky flows like SSO, passwordless login, and MFA, so you're only letting authorized users talk to your AI agent. It handles user sessions, token validation, and RBAC, basically offloading all that security crap from your agent's core logic. Less code for you, fewer chances for auth-related vulnerabilities.

What are the most common ways people screw up Descope integration with a local AI agent? I've seen it all. Hardcoding API keys (classic!), messing up redirect URLs during local dev, not properly validating user sessions or tokens, and just generally ignoring robust error handling. Always use environment variables for sensitive stuff, and for god's sake, make sure your agent is actually verifying tokens with the Descope SDK/API, not just assuming it's all good.

#Quick Verification Checklist (because you will forget something)

• Descope project and application are set up, and those redirect URLs are spot on.
• Descope Python SDK and python-dotenv are installed (and in a virtual environment, right?).
• Descope Project ID and Management Key are in .env and loaded securely by the agent.
• AI agent can actually kick off the Descope auth flow and gets a valid session token back.
• AI agent successfully validates the Descope session token and extracts user info.
• Core AI agent functionalities are properly gated behind a valid Descope session.
• Role-Based Access Control (RBAC) is implemented and you've tested it with different roles.
