You can have up to five fingerprints registered with Touch ID, but only one face logged with Face ID-because you are you. This menu option enables you to configure either Face ID or Touch ID on your device, though you should also have been prompted to set them up alongside a passcode when you launched iOS for the first time on the device. If you open up Settings on your device, you'll see either Face ID & Passcode or Touch ID & Passcode.

Screenshot: Apple via David Nieldįace ID and Touch ID are the two passcode-free ways of signing into an iPhone, and which one is available to you will depend on which model of iPhone you've got. Open the Apple menu, then choose System Preferences and Security & Privacy, and tick the box marked Allow your Apple Watch to unlock your Mac.Īs long as both Mac and Apple Watch are signed in to the same iCloud account, Wi-Fi and Bluetooth are both turned on in macOS, and the Apple Watch has been configured with a passcode, you'll be signed straight into your account when your Apple Watch is brought close to your computer.įace ID works for logging in and in other Apple apps.

The other password-free option is to use an Apple Watch-this works on both desktop and laptop Macs, and with all recent versions of the Apple Watch (check the supported models here). Fingerprint data can be removed or replaced by going back to the Touch ID screen. When you next get to the login screen, all you need to do is place your finger on the sensor and you should be granted access (if there are several user accounts registered on macOS, you may have to select yours first). Up to three fingerprints can be added per user, and you can also use the biometric security method to make Apple Pay purchases on your Mac besides using it to log in. If you do have a MacBook laptop with Touch ID available, you can open up the Apple menu, choose System Preferences, and then select Touch ID and Add Fingerprint.
