Single sign-on and open authorization

Single sign-on (SSO) and open authorization (OAuth) are becoming standards for implementing authentication and authorization. The two are related concepts but serve different purposes in the context of authentication and authorization.

Single sign-on (SSO)

SSO is a mechanism that allows users to log in once and gain access to multiple systems or applications without the need to re-enter credentials. Once authenticated in one application, the user can access other connected applications without needing separate logins.

The key features of SSO are the following:

  • User convenience: Users must only remember and enter credentials once.
  • Centralized authentication: Authentication is typically handled by an identity provider (IdP), which authenticates users and issues tokens.
  • Reduced password fatigue: Users don’t need to remember multiple credentials.

Some examples of SSO Protocols are the following:
