Another question to my fellow Apple users: Have any of you turned on two-factor authentication? And if so, does it interfere with a device's daily use? Apple's page on 2FA says that when you sign in to your Apple ID on a new device, you'll get asked for a 2FA verification code once, and that's it. Supposedly you won't be asked for another code unless you sign out, erase the device, or change your password. Other than that, it's supposed to be seamless and unobtrusive. Is it really that easy?
