SAML Single Sign-On Auth


SAML Single Sign-On Auth add-on IS NOT officially supported since 2020, January 22. You can purchase its source code. Note, the free support is not provided for the item.


Installation of the add-on requires advanced technical skills. It is created mainly for developers to use in further development.


SAML is an XML-based standard for web browser single sign-on (SSO) that eliminates application-specific passwords. SAML uses single-use, expiring, digital “tokens” to exchange authentication and authorization data between an identity provider and cloud application service provider that have an established trust relationship.

Benefits of using SAML:

  • eliminates the possibility of passwords theft/reuse, thereby increasing security
  • improves productivity as a user does not have to enter a password each time they need to access a resource
  • reduces frustration of multiple logins and forgotten passwords
  • compatible with many different cloud application service providers

The SAML Single Sign-On Auth add-on integrates SSO services with your store admin panel, providing you with easy and quick setup.
