A thing or two to know about two-step verification for Apple ID

March 22, 2013

On Thursday March 21, 2013 Apple enabled Two-Step Verification for Apple ID.

Two-step verification is an optional security feature for your Apple ID. It requires you to verify your identity using one of your devices before you can:

  • Sign in to My Apple ID to manage your account.
  • Make an iTunes, App Store, or iBookstore purchase from a new device.
  • Get Apple ID-related support from Apple.


In addition to the Frequently asked questions about two-step verification for Apple ID, there are a few things we found:

  • One phone number can be authenticated to multiple Apple ID two-step verification.
  • Not all SMS-capable phone number can be used, such as Google Voice number and Skype.
    Apple has listed supported carriers for SMS and two-step verification.
  • When verification code sent to an passcode-protected iOS device, user must unlock the device first before the code to be displayed.
  • When verification code sent through SMS to a passcode-protected iPhone, the SMS content might be shown depends on the notification setting.
  • Nexus 4 running Android 4.2.2 Jelly Bean does not display SMS content when it is passcode-protected (including face-unlock and pattern-unlock).

Apple was expected to beef up Apple ID security after the epic hacking of Mat Honan’s Apple ID and Amazon Account.
