# Use Old 403 Authentication Error Status Codes { #use-old-403-authentication-error-status-codes }
Before FastAPI version `0.122.0`, when the integrated security utilities returned an error to the client after a failed authentication, they used the HTTP status code `403 Forbidden`.
Starting with FastAPI version `0.122.0`, they use the more appropriate HTTP status code `401 Unauthorized`, and return a sensible `WWW-Authenticate` header in the response, following the HTTP specifications, <ahref="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1"class="external-link"target="_blank">RFC 7235</a>, <ahref="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized"class="external-link"target="_blank">RFC 9110</a>.
But if for some reason your clients depend on the old behavior, you can revert to it by overriding the method `make_not_authenticated_error` in your security classes.
For example, you can create a subclass of `HTTPBearer` that returns a `403 Forbidden` error instead of the default `401 Unauthorized` error:
