What Does Touch ID Work With on iMac? Touch ID is designed to take the place of entering your password in a variety of situations. As described in the previous section, you can decide exactly what you want to use Touch ID with on your iMac. For example, if you only want to use Touch ID to unlock your iMac, you can select just that option in the Touch ID settings and everything else will still require a password.
Here are the different things you can do with Touch ID on an iMac:
- Unlock your Mac: Instead of inputting your password when you turn on your iMac or wake it up, you can instead use your fingerprint. For extra security, your iMac will sometimes require your password to enable further use of Touch ID in this manner.
- Apple Pay: When purchasing things through Safari, you’ll be presented with your saved payment methods and the option to use Touch ID instead of entering your password.
- iTunes Store, App Store, and Apple Books: When purchasing things through Apple’s own services, you can use your fingerprint to instantly complete the transaction using your stored payment method.
- Password AutoFill: When prompted for a password you have previously saved, you can use Touch ID to automatically fill in the password.
- Fast user switching: If you have fast user switching enabled, you can select your account in the fast user switching menu and then complete the process with your fingerprint instead of typing out your password.
