📝 Test Instructions

1. Register Plugin

plugin add target/release/nu_plugin_auth
plugin use nu_plugin_auth

2. Test Login

# Interactive password prompt
auth login admin

# With password in command
auth login admin testpass --save

# Custom URL
auth login admin --url http://control.example.com:8081

3. Test Logout

# Logout current user
auth logout

# Logout specific user
auth logout --user admin

# Logout all sessions
auth logout --all

4. Expected Output

Login Success:

{
  success: true,
  user: {
    id: "user-123",
    username: "admin",
    email: "admin@example.com",
    roles: ["admin", "developer"]
  },
  expires_in: 900,
  token_saved: true
}

Logout Success:

{
  success: true,
  message: "Logged out successfully",
  user: "admin"
}

🚀 Integration Points

Control Center API

• Base URL: http://localhost:8081 (default)
• Endpoints:
  • POST /auth/login - Authentication
  • POST /auth/logout - Token revocation
  • GET /auth/verify - Token verification (ready)
  • GET /auth/sessions - Session listing (ready)
  • POST /mfa/enroll/{type} - MFA enrollment
  • POST /mfa/verify - MFA verification

Security System

• JWT Auth: RS256-signed tokens (15min access, 7d refresh)
• MFA: TOTP (RFC 6238) + WebAuthn/FIDO2
• Audit: All auth events logged
• Keyring: OS-level secure storage

---

⏭️ Future Work (Not Implemented)

Commands to Implement

• auth verify - Verify current token validity
• auth sessions - List all active sessions
• auth whoami - Show current user from token
• auth refresh - Refresh expired access token

Enhancements

• Auto-refresh tokens before expiration
• Background token refresh daemon
• Session management (revoke specific session)
• Certificate pinning for Control Center
• Token caching in memory (no keyring round-trip)
