Support for FIDO2 Authentication for User Accounts

[CorruptedPhazite]

Adding FIDO2 to accounts would provide a number of benefits including:

• Support for passwordless, second-factor and multi-factor authentication
• Significantly improved account protection from phishing attacks
• Streamlined user onboarding and sign in experience (if passwordless authentication is enabled)

Going through some older issues to clean stuff up. I don't see how this would work here? Users need a password, this isn't something that can be removed. You need to be able to access the account via a console, so we can't just remove password authentication?
