Authenticate users and protect API routes using Clerk's managed authentication. Clerk handles password hashing, session management, MFA, and OAuth flows, letting you secure routes with middleware-based checks that verify user identity before allowing access to sensitive resources.

Yes. Clerk integrates with subscription data to enforce role-based and subscription-level access control. Check user subscription status in middleware or protected components to grant or deny access to premium features and restrict unauthorized users from sensitive operations.

Clerk provides password hashing, secure session cookies, multi-factor authentication, OAuth provider integration, email verification, password reset, and account lockout policies. These features are SOC 2 certified and eliminate the need to implement security-critical logic yourself.

Use Clerk's authentication combined with policy checks in your middleware or route handlers. Verify user identity via Clerk, then enforce ownership policies and role-based access control by checking user permissions against resource ownership and subscription tier before processing requests.

No. Clerk manages sessions automatically through secure session cookies and handles token refresh, expiration, and revocation. Your application receives authenticated user context without implementing session logic yourself.
