Workflow of OAuth
- User visits client (software application) and requests to log in through OAuth of let’s say Facebook.
- Client (software application) requests a browser for access.
- Browser redirects access to Facebook’s authorization server.
- Authorization server asks the user to authenticate himself/herself.
- The user enters his/her Facebook’s login credentials and authorization server matches the credentials and on the successful match, it authenticates the user.
- The authorization server then asks the user to authorize the client (software application).
- User authorizes client (software application) to get data from Facebook.
- The authorization server redirects the user on the browser to the client (software application) with the authorization code.
- Client (software application) uses authorization code with credentials (secret key) to request an Access token and refresh token.
- The client (software application) then goes to the resource server and provides access tokens to get restricted resources from Facebook.
- Now the user is successfully registered with the app and is logged in to the client (software application).
