OAuth Flow
In plain terms
The defined sequence for obtaining an OAuth access token.
Going deeper
An OAuth flow is the step-by-step process (like authorization code or client credentials) by which an app securely gets a token. It governs how access is granted.
Under the hood
Authorization Code with PKCE is recommended for most apps; flows suit different client types.
Examples
Authorization code, PKCE, client credentials, 'Login with Google', token grant.
