How to protect your Apple ID with Two-Factor Authentication

Two-Factor Authentication strengthens the security of your Apple ID by preventing anyone from accessing or using it, even if they know your password. With Two-Factor Authentication, one of your trusted devices generates a one-time code when you make a purchase or sign in to your Apple ID, iCloud, iCloud.com, iMessage, FaceTime or Game Center account on a new device. Two-Factor Authentication is also required for Auto Unlock so you can unlock your Mac by wearing an Apple Watch.

In this tutorial we’ll show you how to protect your Apple ID with Two-Factor Authentication or, if you’re still using the older and less secure Two-Step Verification, upgrade to Two-Factor Authentication.

How to add and remove trusted devices for Apple ID two-step verification

Back in July, we provided you with an overview of Apple’s two-step verification. This is the security method that requires at least two factors of authentication—a password and a trusted device—in order to successfully access an account.

Two-step is a great security method, because it forces one to have physical access to a security key, in this case, an iPhone or an iPad.

Needless to say, we here at iDB highly recommend using 2SV for any account that allows it, Apple ID, or otherwise. In fact, if a service that you’re using doesn’t offer 2SV, I’d seriously think twice about using that service—it’s that important for keeping your data secure.

If you have two-step enabled for your Apple ID, and you should, then you’ve doubtlessly run into the screen that asks you to verify your identify when logging in with your Apple ID. On that screen, it may list some of your Apple devices, and at least one verified phone number. These devices act as security authentication keys.

Have you ever wondered what the requirements are for the devices that are listed here? Have you ever wanted to remove or add a device? In this tutorial, we’ll walk you through managing your iOS trusted devices for two-step verification.
