What I would like to achieve is cloning apps on an non-owner account. Using Android's Work Profile (Shelter app) would be fine, however Android only allows you to enable Work Profile on an owner account. Whereas I would like to set a bruteforce proof password for the owner account that is required at boot, and from there only use non-owner profiles with a 6-digit PIN. So in short: having this extra security layer together with app cloning would be perfection.
An interesting feature that was apparent in beta Android 14 didn't make it to the final release it seems: cloning apps (running multiple instances of the same app, for example Signal). So I'm using the Work Profile (Shelter) option to clone apps, cause all the 3rd party apps seem quite shady Chinese ones. As long as I don't allow the shady app Network permissions it should be fine I guess, but still.. Is there a reason why GrapheneOS didn't adopt this feature yet which apparently is implemented by other OEMs?
Using multiple profiles is not a favorable option. Even though GrapheneOS already made things better like receiving notifactions (partly) across multipe profiles.
I've been using GrapheneOS for a over month now and I'm deeply impressed by it's clever privacy/security solutions and documentation. Please consider donating too here.
