Not possible to sign in with security key on macOS

[ithical]

I'm trying to sign in to the MS 365 desktop apps on macOS (Sonoma 14.3.1).

The tenant only allows "Phishing-Resistant MFA" authentication methods, so Windows Hello for Business, FIDO2 and Certificate-based authentication.

Of these three methods, users are only set up with FIDO2 (Yubikeys).

Users can sign in into the MS desktop applications with their Yubikeys on Windows machines and IOS devices. But on macOS, the MS Office desktop apps and signing into an account in the macOS settings fail:

Users only get the option to sign in with an authentication certificate, which they don't have. No option to sign in with a security key.

Users can sign in through browsers (Safari and Google Chrome tested, both OK).

Apparently it is under development. https://learn.microsoft.com/vi-vn/entra/identity/authentication/fido2-compatibility

It worked on IOS though... but I won't complain about that...

See the supported browsers on below:

Browsers are not the problem.
