Mozilla Accounts need stronger MFA options -- e.g. hardware YubiKeys

[greggo]

Hi. Mozilla advertises FIrefox's password manager as compelling features. And in many ways it is.

But if the passwords are stored in the cloud (they are) and on device (they are) then it seems a serious risk to not offer the ability to lock the passwords behind the strongest security options.

I would prefer to delete most of the login mechanisms for my Mozilla account and *require* a YubiKey hardware device on initial login. This is not supported currently, so the best I can do is passkeys.
