Removing multiple user option

maxo

Hi!
Is there a reliable way to remove the option for multiple users from the settings?
Would be important for parental control for the phones of my kids…
I know its quite a part of many here using GOS, but it makes life way harder with kids who use it to get around their restrictions ;)
Thanks for any end-user doable (adb commands would be fine) suggestions!

maxo Hi, friend. I am also new to GrapheneOS, but the way I understood best practices was: use System account for admin tasks / software install. Create separate daily use profile(s) based on preference.

GrapheneOS aside for a moment; speaking Linux here;

I would highly recommend you follow this effective approach for security. As @Van-de-GraaffeneOS rightly points out, not only would cross-profile snooping be very difficult, it would require authentication for access.

Let me know if you have any other follow up questions and I'm happy to help if I can!

maxo No and ADB commands can seriously mess up your device, GOS themselves don't recommend it.

GOS is not a childrens phone OS, buy them a dumb phone (there are ones specifically branded for children with only a dailer/SMS) if you are concerned, parental control apps are terrible privacy and security wise. Modifying the OS is also insecure.

How are your children guessing the Owner PIN/passphrase?

You have set one, haven't you?!

Thanks people.
Its about their own devices. I know I could just use a locked profile on them but I am searching a way to remove the option totally. If not possible I guess I'll go that way...
I understand there is a way to modify the build.prop file to do it, but I didnt manage to do so successfully yet.
Has anybody experience with that?

Thanks, I understand that. I avoid the "usual" parental control apps, thats obvious.
For parental control I use TimeLimit, which is OpenSource and quite pleasurable for me...

On the English version of that website (which you probably should have linked to, since this is an English language discussion board), there are some solutions listed under "How can I ensure that my child does not get around TimeLimit?". Have you tried those?
