2fa is enabled in essence because when someone tries to hack and take access of your account you can lock it via the link in the email you get if it wasn't you. The issue is is that most people complaining in Meta are waiting for their accounts to be restored to them by an admin which isn't really happening. Better 2fa options will be available on the new forum but the email lock is probably as good as we're going to get on this one.
when exactly is the email sent? what is defined as "tries to hack"? do you mean when the password is changed?
it's not really 2fa because if someone else has the password they can login with just that
I insist proper 2fa should be implemented. it seems simple
