How does the OAuth 2.0 Authorization Code Flow work?

The OAuth 2.0 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 several steps, including redirecting the user to an authorization server, obtaining an authorization code, and exchanging it for an access token.

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) The application exchanges the code for an access token.

What is the purpose of the access token?

The access token is used to authenticate API requests on behalf of the user. It allows the application to access the user's resources without needing their credentials.

Are there any security concerns I should be aware of?

Yes, it's important to use HTTPS to protect the authorization code and access token during transmission. Also, implement proper token expiration and revocation mechanisms.
