# Set up Touch ID for two-step authentication

You can use Touch ID to complete two-step authentication on a Touch ID-capable device, such as a 2017 or newer MacBook Pro or a 2018 or newer MacBook Air.
Follow the steps below to set up Touch ID for two-step authentication on a specific device. You'll still be able to sign in on other devices using SMS, an authentication app, or a hardware security key.
### Before you start
* Enable two-step authentication on your Stripe account using [SMS](/questions/enable-two-step-authentication-using-text-messaging-%28sms%29), an authenticator app, or a hardware security key.
* Configure Touch ID on your Mac and add a fingerprint, see [Apple’s documentation](https://support.apple.com/en-us/HT207054#setup) for instructions.
* Use a modern browser that supports WebAuthn.
### Set up Touch ID two-step authentication for a device
1. Open the [Personal details page](https://dashboard.stripe.com/settings/user) on the Stripe Dashboard.
1. Under the **Two-step authentication** section, click **Add authentication method**.
1. Select **Use Touch ID**.
* If this option is disabled, review the Prerequisites section above.
1. Touch the fingerprint sensor when prompted by macOS. 
1. Enter a name for your Touch ID device. This helps distinguish it from other devices if you add more.
At your next sign-in, you’ll be prompted to use Touch ID for two-step authentication. If don't want to use Touch ID, use your hardware security key or cancel the prompt to authenticate with SMS or your authenticator app instead.
