It would seem that beefing up security is the new cool thing to do, as Apple has also begun implementing a two-factor authentication system for all Apple IDs. The two-factor authentication system requires two pieces to verify the identity of the user, one a password, and the other a physical object on you, in this case the phone.
Once enabled, a 4-digit code is sent via SMS, or the Find My iPhone app when a user successfully signs in with their Apple ID and password on the My Apple ID website, or when making an iTunes, App Store, or iBookstore purchase from a new device. Users are given a 14-digit recovery code to use if they ever forget their password or lose access to their authorized devices. Apple does clarify that even with the two-factor authentication in place, it is the user’s responsibility to keep their log-ins and physical devices secure.
If you are wondering how you can enbable this for your Apple devices, the process is rather simple.
Sign in at My Apple ID.
Select “Password and Security” and enter in the answers to your security questions.
Under “Two-Step Verification,” select “Get Started” and follow the instructions on screen.
You should see the devices you’re using. If not, enable “Find My iPhone” on your device (Settings > iCloud). Click “Verify” and it’ll send you a four digit number.
In the next step you’ll get a recovery key. Print or write this down and keep it in a safe place. This is the only way to regain access to your account if you lose it.
Confirm your recovery key, and then click “Enable Two-Factor Authentication.”
Recently, the two-factor authentication system picked up after Twitter go hacked. Since then, Dropbox and Google have also been employing the new authentication process to secure their services. Therefore, it is no surprise that Apple too has jumped on board.
