# SAML Single Sign-On Integrations

> Describes the Security Assertion Markup Language (SAML) for single sign-on (SSO) integration options.

When you implement <Tooltip tip="Security Assertion Markup Language (SAML): Standardized protocol allowing two parties to exchange authentication information without a password." cta="View Glossary" href="/docs/glossary?term=SAML">SAML</Tooltip> <Tooltip tip="Security Assertion Markup Language (SAML): Standardized protocol allowing two parties to exchange authentication information without a password." cta="View Glossary" href="/docs/glossary?term=single+sign-on">single sign-on</Tooltip> (SSO), it's important to consider:

* Which system(s) will serve as the authoritative source for user profile information if there's ever a conflict between two or more sources.
* What user profile attributes each application needs.
* How user profile information will be distributed to the systems that need it.

You typically set up a SAML federation by configuring SSO initiated by the service provider. The service provider returns a browser redirect so that the user authenticates using the <Tooltip tip="Identity Provider (IdP): Service that stores and manages digital identities." cta="View Glossary" href="/docs/glossary?term=IdP">IdP</Tooltip>. After authentication, the browser redirects the user back to the service provider with a SAML assertion containing information about the authentication status. This is commonly used for consumer-facing scenarios.

You can also configure the IdP to initiate SSO instead of the service provider. In this scenario, the user invokes a URL on the IdP and is prompted to authenticate, then is redirected to the service provider with a SAML assertion. This is commonly used in enterprise scenarios.

We have many [SSO integrations that use Auth0 as the IdP](/docs/authenticate/single-sign-on/outbound-single-sign-on/configure-auth0-saml-identity-provider). We also provide [SSO integrations for other IdPs](/docs/authenticate/protocols/saml/saml-sso-integrations/configure-auth0-saml-service-provider).
