With the latest buld (18298) a new option is available to use a Security Key to login. I have a FIDO2 capable key (Yubikey 5 NFC) and am able to register this device. However, I cannot logon cause no security certificates are installed on the Security key. I assume that I need to register this device to my (AzureAD/Office365) account (like you do with the Autenticator app) but can't find any references to it. Any suggestions?
