Security keys are a more secure second step. If you have other second steps set up, use your security key to sign in whenever possible. If a security key doesn't work on your device or browser, you might see an option to sign in with a code or prompt instead.
- On your iPhone or iPad, download the Google Smart Lock app. If you already have the Google Smart Lock app, move on to the next step.
- Open the Google Smart Lock app.
- Tap Sign in and follow the instructions. If you don’t see this option, skip to the next step.
- Tap the account you’ll use with your key, or tap Use another account. You might need to sign in with your password.
- Follow the instructions to pair your key and device.
After pairing, you can sign in to your Google Account like you normally do. If we need to make sure it’s you, you’ll be asked to press the button on your key.
Note: Currently, iPhone apps like Mail and Calendar only work with security keys used as part of the Advanced Protection program. If you’re part of the Advanced Protection program, learn how to use these apps with a security key. If not, you can use these apps by setting up another verification option, like verification codes or prompts.
