Authorization Code Grant

The Authorization Code Grant is a secure way for apps to access user data without sharing passwords. It works like this: a user logs into a service (like a social media account) and grants permission for an app to access certain information. The app then receives a special code, which it exchanges with the service for a temporary, secure token. This token allows the app to access the data safely and only for authorized purposes. This process ensures user credentials stay private, and access is granted only when the user consents.
