Changes

Testing

This was tested alongside changes to enforce Brute-Force Protection on the passwordless/start endpoint. The error is not currently emitted in this location.

1. block user
2. attempt passwordless login
3. user will be blocked from continuing login since no Brute-Force Protection attempts remain

The current behavior without this change just shows generic error when Brute-Force Protection is enforced:
