Touch ID makes unlocking an iOS device easier. Users no longer have to enter their passcode manually (this has many benefits).
Furthermore, authorizing a purchase or download from the App Store is much easier, too. It can also be applied to applications like PayPal, LastPass, Amazon, and much more. A lot of folks use the fingerprint reader to quickly login into these apps.
Last but not least, Touch ID is extremely useful when buying things with Apple Pay.
Touch ID on Jailbroken iOS
There is no sign of this feature wouldn’t play nice on jailbroken iPhone or iPad. But recently, a few people have reported that Touch ID stopped working after each respring.
For those aren’t familiar with this term, it basically means restarting the device’s Springboard. You usually do this when installing a tweak, switching themes, or making changes to your iPhone.
What to do?
If Touch ID isn’t working on your iPhone or iPad, there is a new jailbreak tweak called Touch ID Respring Fix that does exactly what its title suggested.
- Go on Cydia
- Reload sources
- Install the tweak from the BigBoss repo
The bug that prevents Touch ID from functioning immediately after a respring will be removed after you install this tweak. There is no option to configure.
Touch ID Respring Fix is compatible with devices running iOS 7 – 9.3.3 and the following models:
iPhone 5s or later, iPad Pro, iPad Air 2, or iPad mini 3 or later.
