Don't worry if you're not sure where to start; setting it up is quick and easy, and this guide will walk you through everything you need to know, so let's get this article started.
Where is Touch ID on MacBook, and why is it useful
Touch ID from Apple is a fingerprint recognition system that was first released in 2016. It's built into the power button on compatible MacBook models.
It gives users a fast, secure, and convenient way to access their Macs and approve sensitive actions without the hassle of typing out passwords; here's a couple of benefits:
-
Quick logins. You can unlock your Mac in seconds, no password required.
-
Secure payments. Approve Apple Pay purchases with just your fingerprint.
-
Faster autofill. Instantly enter saved passwords in Safari and other apps.
-
Better security. Your fingerprint data is stored securely, making it more resistant to hacking than traditional passwords.
If you're unsure whether your Mac supports Touch ID, check System Settings > Touch ID & Password to see if the option is available.
The placement of the Touch ID feature can vary slightly depending on your model:
-
MacBook Air (2018 and later). The Touch ID button is separate and located at the top-right of the keyboard.
-
MacBook Pro with Touch Bar. If you're wondering where is Touch ID on MacBook Pro, it's built into the far-right end of the Touch Bar, appearing as a small rectangular button.
Touch ID is also available on some iMacs and Mac minis when paired with an Apple Magic Keyboard with Touch ID. However, this keyboard only works with Macs with Apple silicon (M1 or later) — Intel-based Macs are not compatible.
Now you know what it does and why it's so useful, let's take a look at how to set it up.

Step 4: Test your Touch ID
After adjusting and customizing your Touch ID, all that's left to do is try it out. A good way to test it is to lock your Mac and try unlocking it with your fingerprint.
If it doesn't work, make sure your finger is clean and dry and that the sensor is free from dust or dirt.
How to keep Touch ID working smoothly
It might not sound obvious to some users, but it's actually important to maintain your Mac's performance to ensure Touch ID remains responsive and reliable. A sluggish system can cause delays or unresponsiveness when using Touch ID, especially if your Mac is overloaded with background processes.
Touch ID relies on macOS to process fingerprint authentication quickly. If your Mac is cluttered with unnecessary files or running too many background apps, Touch ID may respond slowly or fail to recognize your fingerprint. Luckily, keeping your Mac in tip-top shape isn't difficult, especially if you use an Apple notarized tool like CleanMyMac.

Here's how to run a Smart Care scan on your MacBook:
-
Open the app and click Smart Care > Scan.

Common Touch ID issues and fixes
Keeping your Mac optimized is one way to prevent Touch ID issues from happening, but if you have issues off the bat straight after setup, you might need to troubleshoot.
Make sure you've checked the obvious — that your finger is clean and that the Touch ID button itself is free from dirt, moisture, or oil buildup on the sensor. A clean fingerprint reader ensures accurate recognition. Also, restart your Mac.
