On the other hand, 2FA opens up the &quot;I lost my phone&quot; customer support channel which might be just as weak.<p>For example, you can turn on 2FA for sending money via Bank of America&#x27;s webpanel. As in, you log in with username&#x2F;password and need 2FA for some restricted actions.<p>Well, phone up customer support and they&#x27;ll remove your 2FA if you can provide them some secret details... all of which are displayed on the webpanel to anyone that was already able to log in.<p>It&#x27;s a joke.
