# Authentication
The Authentication product allows you to verify the identity of users who log in to your online service(s). This is done by using electronic identity methods (ID methods). Integrating with Signicat gives you access to a hub of European ID methods through a single point of integration.
You can integrate with Signicat in three ways, either by using the OpenID Connect (OIDC) standard, SAML 2.0 or our REST API.
