Touch ID lets you log in faster and more conveniently, using your fingerprint instead of typing in all your details each time. Setting it up takes just a moment, and you can turn it off anytime if you prefer.

Below, we'll walk you through how to set up Touch ID login and how to disable it on iOS.

Setting Up Touch ID Login

• After choosing to use Touch ID, you’ll see a checkbox under the login button on the username screen.
• Enter your username and password as usual.
• Enter your postal code.
• A pop-up will appear asking for your fingerprint—simply place your finger on the sensor.
• Once your fingerprint is verified, you’re all set to use Touch ID for future logins.

Note: For security, you’ll still need to enter the last four digits of your postal code when logging in, even with Touch ID enabled.

How to Disable Touch ID Login on iOS

• If you’d prefer to turn off Touch ID, just cancel the Touch ID request when prompted.
• You’ll be returned to the regular login screen and can continue signing in as usual.
