How to set up and use Touch ID on Mac in macOS Sonoma

Touch ID has become more and more popular in the past few years due to the growing need for quick and secure access to devices. This feature is now widely available on Apple devices, including the Mac or Magic Keyboard. In this article, I’ll show you how to set up and use Touch ID on your Mac.

What is Touch ID on Mac?

The biometric authentication system called Touch ID was developed by Apple. Select Mac models and Magic Keyboards have Touch ID built into the power button, which uses your fingerprint to confirm your identity.

The feature’s operation is straightforward because it takes a high-resolution image of your fingerprint, which is later transformed into a mathematical representation and safely stored on the device.

To confirm your identity, place your finger on the Touch ID sensor. Then the device will authenticate you by comparing your current fingerprint to the data already stored. Easy-peasy!

Now that you have a clear picture of what Touch ID is, let us check how to set up Touch ID on Mac.

Benefits of using Touch ID on Mac

Even though the Touch ID setup on your Mac is straightforward, there is still much to learn! Let’s check Touch ID’s complete capabilities and learn how to get the most out of this feature.

1. Unlock your Mac

Using Touch ID to unlock your device without entering your Mac’s password is the primary function of Touch ID. Nevertheless, one of its drawbacks is that after restarting your Mac, you will need to enter your password at least once.

Furthermore, it also enables you to use biometric authentication instead of typing in your password to access password-protected items and it can be one of the most useful features for you if you’re someone who forgets your password frequently.

2. Switch users with Touch ID

You can configure Touch ID to allow quick switching between various users on your Mac. However, the user you wish to switch with must have previously logged into the Mac by entering their password before they can switch to that user account.

In other words, before Touch ID can be used to quickly switch to a user’s account, the latter must have successfully completed the initial login process by providing their password.

3. Password AutoFill with Touch ID

Whether you’re concerned about the security of manually entering usernames and passwords on numerous applications or simply don’t want to take the time to do so, using Touch ID to auto-fill passwords on your Mac makes sense.

Furthermore, by automatically populating your credit card information when asked, this feature can streamline your online shopping experience. It does this by instantly entering your information when you use Touch ID to scan your fingerprint.

4. Purchase items with Touch ID

Touch ID can also be a useful tool for streamlining the purchase process through Apple Pay in addition to its security benefits. By eliminating the need to enter a password, scanning your fingerprint can make the process quick and effortless.

Touch ID can make the process of online shopping a breeze by purchasing an item using Apple Pay. This added convenience makes Touch ID a valuable asset for those looking to simplify their workflow and improve efficiency.

Which Mac models support Touch ID?

You can use Touch ID with MacBook Air (2018 and later) and MacBook Pro (2016 and later).

Can I use Touch ID for other apps or services?

How many fingerprints can I register in Touch ID on Mac?

You can register up to three fingerprints in one user account on your Mac, while the most that can be stored on your Mac are five.

What should I do if Touch ID is not working on Mac?

Is Touch ID secure?

It also makes use of a secure enclave, a unique piece of hardware that stores your fingerprint information while keeping it isolated from the rest of your device’s data.

However, just like any other security measure, Touch ID is also not foolproof and can potentially be breached by hackers or attackers. Tell me in the comments section what your thoughts are about Apple’s Touch ID.
