What are the steps in the OAuth2 Authorization Code Flow?

The OAuth2 Authorization Code Flow involves several key steps: 1. The user is redirected to the authorization server. 2. The user logs in and grants permission. 3. The authorization server redirects back to the client with an authorization code. 4. The client exchanges the authorization code for an access token. 5. The client can now use the access token to access protected resources.

Can you explain each step in more detail?

Sure! 1. Redirect to Authorization Server: The client redirects the user to the authorization server's login page. 2. User Login and Consent: The user logs in and is asked to consent to the requested permissions. 3. Authorization Code: After consent, the authorization server redirects back to the client with an authorization code in the URL. 4. Token Exchange: The client sends a request to the authorization server to exchange the authorization code for an access token. 5. Access Protected Resources: The client uses the access token to make API requests on behalf of the user.

What is the purpose of the access token?

The access token is a credential that allows the client to access protected resources on behalf of the user. It contains information about the user's permissions and is typically short-lived for security.

Are there any security concerns I should be aware of?

Yes, some security concerns include token leakage, using HTTPS to protect data in transit, and implementing proper token expiration and revocation mechanisms.
