This is the fast changing digital world, where security has become the subject of optimum importance. Even slight mistake or carelessness can cause irreparable damage. In the wake of the rampant cyber crime and jaw-dropping audacity of hackers in stealing confidential data, it pays to be extra caution.

To offer an utmost safeguard to your Apple ID or iCloud account, Apple has introduced Two-Factor authentication. When enabled, it will allow you to access your account only on the devices you completely trust. The best thing about it is that even if someone has succeeded in stealing your password, he cannot have the access to your account.

How to Turn On Two-Factor Authentication for Apple ID on iPhone and Mac

With Two-Factor authentication, whenever you sign into a new device like iPhone or Mac for the first time, you will have to not only enter the password but also authenticate it using the six-digit verification code which displayed automatically on your trusted device.
As for instance, if you sign in to your account on your iPad, you will be prompted to enter the six digit code which will appear on your iPhone, which you have trusted.

Currently, Two-factor authentication is available to all iCloud users who have at least one device running iOS 9 or OS X El Capitan or later.

Two-Factor authentication is different from Two-Step Verification. For more information, check out our post on how to turn on Two-Step Verification.
