Implementing Resource Owner Password Credentials Flow

The Resource Owner Password Credentials flow in OAuth 2.0 is used when the client application can obtain the user's username and password and directly exchange them for an access token. Unlike other OAuth 2.0 flows—where the client application interacts with the authorization server through redirections, callbacks, and authorization codes—the Resource Owner Password Credentials flow involves sending the user's credentials directly to the authorization server.

In this chapter, you can find details about the implementation of the Resource Owner Password Credentials flow.
