Microsoft Entra ID (Azure AD)
Microsoft's cloud identity platform that provides OAuth2/OIDC SSO, MFA, conditional access, and user/group management for enterprise Microsoft 365 and custom applications.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Use MSAL; never store tokens in logs; use certificate credentials over client secrets for production service principals
⚡ Reliability
Best When
Building enterprise apps in the Microsoft ecosystem where users already have Azure AD identities.
Avoid When
Your user base doesn't have Microsoft accounts or Azure AD licenses — provisioning costs add up.
Use Cases
- • Authenticate users via OAuth2 authorization code flow and acquire tokens for Microsoft Graph API calls
- • Register background service principals and use client credentials grant for daemon app auth
- • Implement conditional access policies via Graph API to enforce MFA for sensitive operations
- • Sync user provisioning/deprovisioning from your app to Azure AD via SCIM 2.0 endpoint
- • Query group memberships and assign app roles to users via Microsoft Graph API for RBAC
Not For
- • Consumer-facing apps without Microsoft 365 dependency — use Clerk, Auth0, or Cognito
- • Simple API key authentication — Azure AD adds OAuth complexity not justified for internal tools
- • Non-enterprise environments where multi-tenant consent flows create deployment friction
Interface
Authentication
Microsoft identity platform v2.0; client_credentials for daemon apps; auth code + PKCE for users; MSAL library recommended
Pricing
Core auth is free with Azure subscription; premium features (conditional access, PIM) require P1/P2 license
Agent Metadata
Known Gotchas
- ⚠ Access tokens expire in 1 hour — agents must implement MSAL token cache or silent refresh; don't store raw tokens
- ⚠ Admin consent required for most Microsoft Graph scopes — agents cannot self-consent; must coordinate with tenant admin
- ⚠ Multi-tenant apps require tenant-specific endpoints or /common/ — wrong endpoint causes AADSTS errors
- ⚠ Client credentials grant cannot access user-delegated resources (e.g., user's calendar) — different permission model
- ⚠ Conditional access policies can block token issuance and return AADSTS65001 — agents must handle CA policy failures gracefully
