# Single sign-on

> Section index for XBOX single sign-on (SSO), showing how XBOX network sign-in unlocks your custom services and how to configure it in Partner Center.

Single sign-on enables a player using your title to sign into your services by using their XBOX sign in.
A player that is signed into the XBOX network (also known as XBOX Live) can run an app or game for your service without having to log in a second time using a different account credential specific to your service.
