I’m trying to do a PoC of #Passkeys using #EntraID and the #Microsoft Authenticator app on iOS. I’ve been able to successfully create and register Passkeys on *unmanaged* iOS devices. But on supervised devices managed by Intune it always fails to register the passkey with Entra ID. I get all the way to the end of the process and receive “registration failed for an unknown reason”.
I’ve tried the three methods documented by Microsoft and they all result in failure—directly from the Authenticator App, from the browser (Edge on iOS) and the cross device method using Edge on Windows 11 generating a QR code.
Any thoughts on why this would fail like this?
