WARNING: If you plan to install this on any device (primary or secondary) ensure that Two-Factor authentication is DISABLED and for the mean time use Two-Step authentication as some users are reporting that they have been locked out of their Apple account and Apple themselves can do nothing about it.
The security methods above are different and NOT the same!
I'm confused how you can be locked out of your account with two factor authentication when you have security questions/ recovery keys etc. How is the beta messing this up?
