How do you implement OAuth 2.0 authorization code flow in Java?
In OAuth 2.0 authorization code flow, the client application first redirects the user to the authorization server, where they grant consent. The server then redirects the user back with an authorization code that the client exchanges for an access token.
Thatâ€™s correct. The authorization code flow is the most secure flow in OAuth 2.0, as the access token is never exposed directly in the user agent.
Can you explain how the client uses the authorization code to obtain the access token, and what security measures are involved?
