Single Sign-On

Salesforce has its own system of user authentication, but some companies prefer to use an existing single sign-on capability to simplify and standardize their user authentication.

You have two options to implement single sign-on—federated authentication using Security Assertion Markup Language (SAML) or delegated authentication.

Identity Providers

An identity provider is a trusted provider that lets you use single sign-on (SSO) to access other websites. A service provider is a website that hosts apps. You can enable Salesforce as an identity provider and define one or more service providers. Your users can then access other apps directly from Salesforce using SSO. SSO is a great help to your users—instead of having to remember many passwords, they only have to remember one.
