How to Enable Two Factor Authentication for Apple ID?

What is Two-Factor Authentication?

Security is the most important factor when you use personal information on a computer. In earlier days, the practice was to enter the username/password and verify the details with an additional security question. This still have a problem of stolen password and security questions stored in database. Nowadays, instead of security question you need to verify the access with additional passcode generated and sent to one of your other device dynamically.

In 2017, Apple followed Google’s footstep by adding an extra layer of security to protect your Apple ID as well as your iCloud data. It started with the iOS 10.3 beta version and had ultimately remained a part of the iOS and macOS updates since then.

How Two Factor Authentication Works?

Whenever you login with your Apple ID from an unknown device, Apple will send a verification code with the location map to your trusted devices. The trusted devices could be your iPhone, iPad or Mac which you have confirmed beforehand. You can check the map location and allow or block the login attempt. Alternatively you can also manually get verification code from the trusted device to use on new device.

This is an additional layer of security that helps to protect your account even though someone knows your password. Remember that when you confirm the login with verification passcode on a new device, you are essentially adding the new device as your trusted device. So, only trust the device if it is your own.

When you have multiple trusted devices for your account, Apple will send different passcode to all your trusted devices. You can enter any of the passcode and confirm the login attempt.

Why You Need Two Factor Authentication?

Besides security, you need two-factor authentication for many continuity features to work. For example, when you want to use continuity camera feature between your iPhone and Mac then you should have enabled two-factor authentication for your Apple ID.

If you have security question on your old Apple account, Apple will hold the question/answer for two weeks time after you enable two-factor authentication. After that the security question will be deleted and also you will not be able to disable two-factor authentication on your device.

So, it’s pretty clear that two-factor authentication is a new security concept mandatory and not optional for users. Also as an additional feature, you can reset or change the password of your Apple ID from the trusted devices.
