Allow a security key for Firefox sync 2FA

[Something]

I use Firefox sync to sync my securely generated passwords, so if someone got access to it, they'd have access to a huge number of accounts that don't support 2FA. I would like to use a security key to log in but it isn't supported. Please implement the WebAuthn API for Firefox accounts.

Add Security Key Support to Firefox Account

I use Firefox Sync in order to synchronise my browser data across devices. In order to have my account properly protected, I'd prefer using a security key over an TOTP app which is currently the only possible method for two-factor authentication.

Therefore, I would like to request security key and passkeys support for Firefox Account.
