Authorization Code Flow

The Authorization Code Flow is a secure process that allows a user to grant a third-party app access to their data without sharing their password. The user logs in directly with the service (like Google), which then gives the app a temporary code. The app exchanges this code behind the scenes for an access token, which it uses to access the user's data. This method ensures passwords stay private, and access is controlled through tokens that can be managed or revoked, maintaining security and user control.
