Identity services make it simple, secure and reliable for your users to sign in to each of their enterprise cloud applications and for you as an administrator to manage usage across your organization.
As an administrator, you can configure identity services to provide your users with a unified sign-on across all their enterprise cloud applications. Once you configure your users' enterprise cloud applications to use Security Assertion Markup Language (SAML) 2.0, they can use their G Suite credentials to sign in to enterprise cloud applications via Single Sign-On (SSO).
The user provisioning feature in identity services makes user provisioning and deprovisioning easy. Once you've set up your applications for SSO, you can set up user provisioning to create, modify, or delete a user's identity once in G Suite, and have the changes to that identity reflected in all applications.
