FAQ
What does this tool tell you?
The OAuth 2.0 Flow Reference covers Authorization Code + PKCE, Client Credentials, refresh token rotation, state parameter CSRF protection, and the deprecated Implicit flow.
What affects the result most?
Authorization Code: web apps with server — most secure, access token never exposed to browser. Authorization Code + PKCE: SPAs and mobile — replaces Implicit flow, code_verifier never sent to server. Client Credentials: machine-to-machine — no user, client authenticates directly.
How should I use the result?
Use this tool to orient quickly to the concepts, field names, or values you are about to look up in a full specification or vendor documentation. It summarizes the common cases; the authoritative source remains whichever standard or vendor doc defines the values themselves.
