Two-factor authentication is a feature that secures your device from being accessed if it is lost or stolen. It is also a great hindrance for anyone with diminished mental acuity. So this should only be enabled if you still have a sharp mind and a good memory. If you don’t enable two-factor authentication, then you probably should chain your mobile device to your body, right?

Once two-factor authentication has been enabled and active for two weeks, it cannot be undone. Not even by Apple.

Wait! It can be undone. However, the only way to deactivate two-factor authentication is to deactivate the device. This means restoring it to its factory settings - and it wipes the device clean. When you turn it back on and set it up again, do not enable two-factor authentication.
