Describe the bug

Just wanted to ask a simple question, maybe some advice. I'm using LiveContainer to duplicate an app, but after trying it, the app detects the same device ID after deleting and reinstalling it inside LiveContainer. My solution is to delete the app, uninstall LiveContainer, and reinstall it to get a different DeviceID/Keychain. So is there a simpler way? If we install app A, B, C, it will generate a different DeviceID/Keychain.

example This is an image of the request in the API of the application I am using

Instructions to reproduce

What version of LiveContainer and iOS are you using?

3.6.1

Other info

No response

I came to find if there was a discussion about this as well. Would love an option to generate a new UDID in the settings.

We can't help you without even knowing what the app is

@hugeBlack it's not specific to any app, but to LiveContainer.

I discovered this with "Board Kings".
Install it using LC and open it, it shows a UDID right at the top when it's loading. Deleting the app in LC and reinstalling will show the same UDID at the top when loading it again. Creating a new app container doesn't solve it either.

However if you delete and reinstall both LC, then the game within LC, it will show a new UDID when loading.

So I assume it's something to do with the "virtualization". It would be nice to be able to "reset" LC and get a new UDID instead of having to delete and reinstall

According to Unity, this device id is acquired from [UIDevice identifierForVendor] which only changes if the app is completely reinstalled

@hugeBlack commented on GitHub (Sep 20, 2025): According to [Unity](https://docs.unity3d.com/6000.2/Documentation/ScriptReference/SystemInfo-deviceUniqueIdentifier.html), this device id is acquired from [`[UIDevice identifierForVendor]`](https://developer.apple.com/documentation/uikit/uidevice/identifierforvendor?language=objc) which only changes if the app is completely reinstalled
