Jailbreak Tweak 'AppLocker' Locks Individual Apps With Touch ID

Following the December release of the evasi0n jailbreak for iOS 7 devices, several new jailbreak tweaks for the iPhone 5s are in the works, including a newly updated version of AppLocker that is designed to take advantage of the Touch ID sensor of the iPhone 5s.

AppLocker is a tweak that has existed for some time, allowing users to lock individual apps with a password. With iOS 7 and an iPhone 5s, AppLocker is able to lock and unlock apps using Touch ID's fingerprint recognition capabilities. iDownloadBlog has a detailed video of the tweak in use:


AppLocker is only able to access fingerprints that have been entered into the iPhone 5s via the Touch ID menu in the Settings app, and different fingerprints are not distinguished by the system, so there is little setup needed to install the tweak. As demonstrated in the video, app unlocking works as seamlessly as standard device unlocking with Touch ID.

At the current point in time, Touch ID on non-jailbroken devices is limited to unlocking the phone and making purchases in the App Store. It is likely that Apple will expand the use of Touch ID in the future, but it remains unknown whether Apple has plans to release a Touch ID API that would allow the functionality to be built into individual apps as in the AppLocker jailbreak tweak.

The security implications of the Touch ID-supported AppLocker tweak are unknown, as Apple has said that all Touch ID data (in the form of a mathematical representation of a fingerprint) is stored in a "Secure Enclave" inside the A7 processor that is walled off from the rest of iOS and unavailable to iOS or other apps.

According to the developer of the tweak, who spoke to Cult of Mac, AppLocker is not accessing Touch ID data, but rather confirming that a finger is authenticated. "All I am doing is asking iOS, 'Hey, is this finger authenticated?' and I get either a 'Yes' or a 'No,'" he said.

The Touch ID functionality in AppLocker 2.2 is currently available for download on jailbroken devices via the ModMyi repo. The update is free for current AppLocker users and $0.99 for new purchasers.

Why is the calculator app locked in the video? Is it his secret naughty number stash? Does he type in "34 + 35" and giggle to himself?


It's called a Demo :rolleyes:

this might not be terribly useful on a phone but an ipad is a very different story. Before ipad air came out I was sure it would have touch id and it would be used as some kind of multi-user authentication tool along the lines of this jailbreak app. I still expect it to happen in ios 8 and the next ipad.


Multi user iPad? Put down the crack pipe.

Apple don't want to sell you one iPad for many users, they want you to buy one iPad each.

This is really cool. Too bad it didn't save my 14-year-Apple-only household from going Android.

Family of 6. Nobody wants to go back to iOS after using Android. Nobody.

All because Apple refuses to:

Implement multi-user accounts
Release a bigger-screen iPhone
Let users revert out of iOS 7
Allow more customization options

I was planning on jailbreaking; no need now.

Even the wife gave up her iPad/iPhone combo for a Note 3, and is happier than I ever thought she could be. She used to be fused to the iPad. All. The. Time. Funny thing is that I'm the family IT guy and she came to me wanting the Note 3.

From my perspective, this could be a troubling sign for Apple and should be addressed by them.

Don't know about you, but my whole family did the exact opposite. They were on android, and couldn't stand it. Nothing ever worked right. They love their iDevices cause they just work. And they can still customize it cause I jailbreak them for them.

Pardon my ignorance, but Android allows multi user accounts on a single device? Can you tell me how this works?

Yes. It works very well, and very simply (http://www.dummies.com/how-to/content/how-to-add-another-user-to-your-android-tablet.html).

Edit: To be clear, I'm not insinuating that you are a "dummy", the link was purely a top hit on Google that explained it well.

Thanks for the link. Yes I do image home screen widgets and backgrounds are changed per user, but what I didn't see mentioned is whether every app keeps its own database for each user (ie, Gmail, photos, etc.).
