Apple recently debuted a two-factor authentication approach for securing Apple IDs from hacking; however, this has been limited to authenticating on Apple’s Web site or making purchases using iTunes. Now Apple has expanded this security measure to work with its text, voice, and video messaging services.

This means that if you are using iMessage or FaceTime, then for new logins on an unknown device (one you haven’t used before), you will need to supply a security code that will be texted or otherwise sent to another verified device. While secure, one might also run into issues where such authentication does not work as expected, in which case a recovery key can also be used to authenticate.

This development greatly helps secure Apple’s devices, and is progressively important as more and more confidential and personal information makes its way onto the devices. This is true not only for iMessage and FaceTime where someone with unauthorized access could fake your identity to get information from your contacts, but also as Apple breaks more ground into personal finance and health markets.

When fully implemented, your login will require these steps:

1. Sign into iMessage or FaceTime on a new device.
2. Receive a message that you need to enter a code sent to another of your iOS or Mac OS devices.
3. Enter this code when received.
4. Continue to access iMessage and FaceTime on your new device.
