# Single sign-on
Single Sign-On (SSO), is an authentication scheme that allows a user to log in with a single ID to any of several related, yet independent, software systems.
# Global SSO Settings
Slug: The slug allows the configuration of your unique Virtuoso URL, if the slug is configured as <slug> the unique login URL will be https://app.virtuoso.qa/#/<slug>/login.
Enforce SSO Authentication: Enable this option if you want to force SSO authentication (Google or SAML) for your unique Virtuoso URL disabling the password URL.
Enable SAML integration: Toggle this option if you want to enable authentication through a SAML identity provider. Further configuration is needed to activate this option.
SSO / SAML authentication options are only available if your organization already has a slug configured. Otherwise, the toggles to activate them will appear as disabled.
The enforcing of SSO authentication will work only for your organization. If a user belongs to several organizations they will still be able to login with the options supported by the other organizations.
