How do you implement OAuth 2.0 authorization code flow in Java?
The OAuth 2.0 authorization code flow involves sending an authorization code to the backend, which then directly exchanges it for an access token from the authorization server.
Thatâ€™s partially correct. While the authorization code is sent to the backend, it is important that the backend exchanges the code for the token using a secure client ID and secret to ensure confidentiality.
Can you explain how the clientâ€™s credentials are kept secure when exchanging the authorization code for an access token?
