And now you have to log into your email with a Passkey that probably you lost at the same time you lost your Passkey to the original site (e.g. lost or stolen device).
If you are not using Passkeys for your email (and the site supports that type of account recovery), then you still have only the security of passwords, just with additional steps.
Well, it puts people in a bind. The current status quo of TOTP 2FA with recovery codes is bad, but it's probably the best we have - because applying passkeys to your primary e-mail is beyond stupid at this point, it's putting your digital life in mortal peril.
