# Single Sign-On

This section provides instructions on integrating Single Sign-On (SSO) user authentication services to your Spark instance. This can be used instead of the [Tenant administration](/tenant-administration.md) functionality to manage users and user groups.

Spark uses [Keycloak](https://www.keycloak.org/) for Identity and Access Management (IAM). Keycloak has the ability to be integrated with many commonly used IAMs.

If you cannot find instructions for your identity provider, please contact [Support](/support/support.md).
