How does the OAuth2 Authorization Code Flow work?

The OAuth2 Authorization Code Flow is a process that allows a user to grant a third-party application access to their resources without sharing their credentials. It involves redirecting the user to an authorization server, where they log in and approve access.

What are the main steps involved in this flow?

The main steps are: 1) User is redirected to the authorization server, 2) User logs in and grants permission, 3) Authorization server redirects back with an authorization code, 4) Application exchanges the code for an access token.

What is the purpose of the authorization code?

The authorization code is a temporary code that the application uses to obtain an access token. It ensures that the application can securely request access without exposing user credentials.

Can you explain the difference between access tokens and refresh tokens?

Access tokens are used to access resources on behalf of the user, while refresh tokens are used to obtain new access tokens when the current one expires, without requiring the user to log in again.
