Single sign-on (SSO) is an authentication methodology that allows a user to log in to one of several related, but independent, software systems with a single ID.

True single sign-on allows the user to sign in once and access services without having to identify themselves again. It’s a convenient way to access multiple applications without having to remember multiple usernames and passwords.

Retailware supports Single Sign On based on Microsoft Entra (formerly ADFS) and oAuth 2.1, among others.
