Securing your online accounts is essential to protecting your personal information, especially if you re-use passwords. One way to add another layer of security to your accounts is to use two-factor authentication (2FA) with the iPhone code generator built into iOS.

Note: Websites that support the built-in 2FA iOS code generator will either provide you with a setup code or a QR code. Facebook offers both, but using a QR code is easier because you just need to scan it with your iPhone’s camera.

What Is the iOS Version Required to Use the iPhone Code Generator?

Your iPhone needs to run at least the iOS 15 to use the iPhone code generator. If you have an iPhone X or newer, you can update to and run iOS 15 to enjoy its features, including the built-in code generator for 2FA when logging in to websites or applications that support 2FA.

To check which iOS version you’re running, go to “Settings -> General -> iOS Version.”

You need to have iCloud activated to generate login codes for your online accounts. If you don’t have saved passwords in iCloud, you won’t have access to the built-in code generator on your iPhone.

Tip: if you want to store your passwords without using iCloud, check out these password managers for mobile, Web, and desktop.

Frequently Asked Questions

Which websites support setting up 2FA with my iPhone's built-in code generator?

You can use the 2FA Directory to look up and verify whether the websites or apps you use support 2FA. There are websites or apps that support specific authenticator apps, SMS or phone call authentication, and hardware authentication.

How do I remove the iPhone code generator from an account?

To remove the iPhone code generator from an account, first disable 2FA on that account. If you remove it from your iPhone’s settings first, you’ll get locked out of your account, and you’d need to use a backup or recovery code.

For example: you set up 2FA for your Discord account. Disable it there, then proceed to your “iPhone’s Settings → Passwords → saved login information → Edit → Delete Verification Code.”

Can I generate a backup code if I lose access to my iCloud account?

You can generate a series of backup codes or recovery codes from the platforms to gain access to your account if you lose your iPhone. Each code can only be used once, and it’s possible to generate a new set. If you also lose access to these backup and recovery codes, your last resort would be to contact the platforms running your account. You’ll need to prove account ownership to regain access to your account.
