= Optional and group claims for Entra ID application registration

[role="_abstract"]
The `email` and `preferred_username` Entra ID optional claims provide {product-title} with the information it needs to create user accounts. Group claims enable group-based access control.

In addition to individual user authentication, {product-title} provides group claim functionality. This functionality allows an OpenID Connect (OIDC) identity provider, such as Entra ID, to offer a user's group membership for use within {product-title}.
