OAuth 2.0
You have most likely interacted with OAuth already via "Login with Facebook" or "Login with Google". Either of these options allows you to authenticate yourself without having to use a separate username and password for a particular service, just piggy-back off of another service's authentication.
Registration
Our service that intends to use OAuth needs to register itself with the resource server, receiving their own client ID and client secret.
Redirect URI
Our service also needs to declare to the resource server a redirect URI. This tells the resource server where to bring users back to after logging with their authentication system.
Code Generation
Service pulls up a custom resource server login page unique to their client ID and redirect URI.
Client returned a new code upon successful login
Client will use this code to fetch a session token from the resource server
