How to fix Touch ID on your supported Apple deviceHow do I fix Touch ID? If you can't access your device, try these troubleshooting tips!
Touch ID is Apple's fingerprint identity sensor. It allows you to unlock your device, log in to apps, use Apple Pay, and make purchases from the App Store by touching and briefly holding your finger against the sensor. When it works, it's magical and you want it everywhere — your car, your house, your yacht, your one-person rocket to Mars — but when it doesn't, you want to throw your iPhone (or Mac) across the room.
What can make Touch ID failures even more frustrating is figuring out why it's failing in the first place. From the outside, it seems like the stereotypical black box. A fingerprint goes in and then it either works or doesn't, and if it doesn't, there's no way for us to see what went wrong, why, or how to fix it. Maddening.
There are, however, some things you can do to make it work better and more often.
