 ## 6. Add a filter for issuing challenge nonces
 
-A REST endpoint that issues challenge nonces is required for authentication.  
-Since this step is part of the authentication flow, it is implemented as a Spring Security filter instead of a regular controller. The filter must support `POST` requests.
