This is the routing entry point for authentication, sessions, and authorization boundaries.
Use it to decide whether the issue is mainly login mechanics, object-level authorization, browser trust boundaries, or identity protocols such as OAuth/JWT/SAML before going deeper.
When to Use
The target includes login, registration, password reset, 2FA, sessions, JWT, OAuth, or SSO
You suspect object authorization flaws, cross-tenant access, cross-origin reads, CSRF, or protocol misconfiguration
You need to decide whether to test authentication or authorization first
assertion wrapping, signature validation, audience, ACS boundaries
Recommended Flow
First confirm the authentication model and session boundaries
Then confirm object-level and function-level authorization
Then move to token, cross-origin, and protocol details
If enterprise federation exists, continue with OAuth, OIDC, or SAML topics
