You can add additional fingerprints to Touch ID equipped Macs, providing the option for more than one fingerprint to unlock the Mac, be used for Apple Pay, and to make purchases from the iTunes and App Store.
Obviously the ability to add a new fingerprint to Touch ID on the Mac requires a Mac with a Touch ID sensor within the Touch Bar, currently limited to the newest model MacBook Pro but which will likely roll out to other Mac hardware and perhaps even with an Apple external keyboard in the future.
How to Add Additional Fingerprints to Touch ID on Mac
- Go to the Apple menu and choose “System Preferences”
- Select “Touch ID” from the options
- Choose “Add a Fingerprint”
- Rest the new finger (or toe or other body part…) on the Touch ID sensor and tap a few times following the onscreen instructions
- When the fingerprint sensor is filled out and it says “Touch ID is Ready” click on “Done” to add that fingerprint to Touch ID on the Mac
- Optionally, repeat the process with an additional fingerprint
The Mac allows you to add up to five different fingerprints to Touch ID.
Adding additional fingerprints is convenient, but it can also be helpful to add the same fingerprint more than once on the Mac just like doing so can improve the reliability of unlocking Touch ID on iPhone and iPad, particularly during different seasons where a skin may be more dry or moist.
