Apple Two-Factor Authentication is a terrific method to safeguard your account.

In short, you can easily use Apple 2-FA using Password & Security feature and selecting Turn On Two Factor Authentication.

What’s going on here?


Two-factor authentication guarantees that only you have access to your account in the case of a security compromise. Potentially malicious devices display a six-digit verification number or send it to your phone. The code validates your confidence in the new device. To begin, enter your password and your phone’s verification number. Consider this.

Because your password alone is no longer adequate to protect your Apple ID and all of your personal information, you should use two-factor authentication as soon as possible.

You won’t be asked for a verification code on that device again unless you check out of your account, delete the device, or change your password for safety reasons. Your browser will no longer ask for a verification code the next time you log in from that device.

You can depend on these Devices

One of the advantages of using two-factor authentication on an iOS 9- or later device is that it is now considered a “trusted” device. When you sign in on another device or browser, we may ask for an Apple verification code to verify your ownership of the device. You must have watchOS 6 or later installed on your Apple Watch in order to get verification codes when signing in with your Apple ID.

Trustworthy phone numbers for your convenience

Text messages or automated phone calls from a trusted phone number may be used to send verification codes. At least one trusted phone number is required for two-factor authentication.

It’s a good idea to double-check other people’s phones, too, such as those of family members or close acquaintances. As a last resort, you may dial this instead of the phone number you normally use to contact us.

Codes for verifying information

Whenever you use your Apple ID on a new device or browser, a verification code is delivered to your trusted device or phone number. Your trusted device’s settings might potentially provide you with a verification code.

Your iPhone, iPad, or iPod touch’s password is not the same as the verification code.

iOS Two-factor authentication: What is it and how does it work?

Only trusted iOS devices may access your account with two-factor authentication. Your trusted iOS device will automatically display a six-digit verification number whenever you use your Apple Account on another iOS device.

Even if your buddies know your login details, this is an important component to keep safe.

For the sake of argument, let’s pretend you now use an iPhone and just bought an iPad. You’ve used the same account on both your iPhone and iPad to log in. It will ask for a six-digit verification code, which appears on the iPhone after logging in.

This makes your device protected by providing an extra step.
