# Authentication and Authorization ## Workflow 1. Identify actors, identity provider, session/token model, trust boundaries, and protected resources. 2. Use mature framework/provider primitives instead of inventing cryptography or password storage. 3. Keep credentials/tokens out of URLs, logs, client bundles, and source control. 4. Enforce authorization server-side for every privileged action/object. 5. Review login, logout, refresh/session expiry, password/reset/recovery, email/phone verification, and account-disable behavior relevant to the product. 6. Protect against enumeration, brute force, replay, CSRF/session fixation, insecure redirects, and token leakage as applicable. 7. Use secure cookie attributes and appropriate token expiry/rotation. 8. Test anonymous, normal-user, privileged-user, expired-session, revoked/disabled-user, and cross-tenant access cases. Authentication proves identity; authorization decides permitted actions. Do not treat them as interchangeable.
