Adding YubiKey Support to Azure AD and Edge on iOS/iPadOS
YubiKey's 5Ci security keys allows password-less authentication via Lightning connector. It's the first security key that can plug into a iPhone or iPad Lightning port and USB-C port. Several apps supports authentication such as Brave, a browser app based on Chromium.
It would be great if Azure Active Directory and Edge supports the YubiKey for password-less authentication.
There is also an upcoming SDK to support the new NFC authentication capabilities in iOS. This will allow FIDO2 authentication over NFC and Lightning as well.
iOS/iPadOS 13.3 and higher includes full support for FIDO2:
My original user voice (from October 2019) was scoped on Yubikey because a 3rd party SDK was only available for integration at that time. From now on it should be possible to support all FIDO2 security keys.
While generally supporting the idea I would't limit it to YubiKey but FIDO2 in general.
The beauty of that standard is the vendor agnostic approach.
On top I see the most important application that needs FIDO2 support on iOS is MS Authenticator.
his will open up the passwordless authentication to all Microsoft Apps on the device.

Need to see security key support, but would preference would be for U2F integration as MFA for Azure AD across Windows and iOS/iPadOS
