# SSO

4WS.Platform supports external/SSO/federated SSO authentication mechanisms, that hold usernames and passwords and let the credential to be stored in a central system, without replication. Anyway, to make 4WS.Platform work correctly the users and roles must be synchronized or provisioned.\
The following authentication providers are currently available:

* [Identity management in Platform](sso/ee6-1-identity-management-in-platform)
* [external LDAP or Active Directory](sso/ldap)
* [Google SSO](sso/google-sso)
* [Custom SSO](sso/custom-sso)
* [Firebase (mobile)](sso/firebase)
