Use your phone's built-in security key

You can set up your phone’s built-in security key to safely sign in on devices running current versions of Chrome OS, iOS, macOS, and Windows. This helps protect your account from hackers, even if they’ve stolen info like your password.

When there's an attempt to sign in to your account, Google can check whether there's a Bluetooth signal between that device and your phone’s built-in security key. This Bluetooth check assures Google that you and your phone are physically present and that the sign-in attempt isn’t coming from someone else in a different location.

To set up your phone as a security key, you need an iPhone running iOS 10+. Learn how to update your iOS version for each account that you want to protect.

If your phone is eligible, Google will automatically use your phone’s built-in security key for additional protection when you sign in to new devices.

Important: You can only have one built-in security key on your account. If you have more than one eligible phone, you’ll need to choose one. You can switch to a different eligible phone at any time.
