eduMFA Passkeys: missing expiration flag may allow replay attacks and reuse of old challenges
In eduMFA < 2.9.1 userless Passkey/WebAuthn challenges might be replayed and do not expire
Fixed in eduMFA >= 2.9.1 by adding validity information to the userless challenges.
No known workarounds besides disabling userless login altogether.
