# SCIM authentication

You must authenticate all System for Cross-domain Identity Management (SCIM) requests using OAuth 2.0 bearer token authentication.

Bearer tokens are evaluated using access token validators. The `HttpRequest.AccessToken` attribute supplies the validation result to the policy request, and the `TokenOwner` attribute provides the user identity associated with the token. Policies use this authentication information to affect the processing of requests and responses.
