Back when Google unveiled multi-user support with Android 4.2, one of the first question on many users' minds was how will root access be handled on secondary user accounts? It was a short answer, actually: it wouldn't. Superuser managers like SuperSU simply wouldn't run on anything aside from the primary user.


However, Android developer Chainfire – the mastermind behind SuperSU – knew that it could be done. It's been clear that he has kept this venture on the forefront of his mind, and he's finally broken the barrier. Today's update brings full multiple user support on Android 4.2, so every user on a single device can enjoy the benefits of having a rooted system.

Aside from that, the update also packs in support for x86 devices.

If you're a rooted user not using SuperSU, it's probably time to give it a look. For my personal devices, I wouldn't even considering using another app.

    Is there an option to disable superuser rights on a secondary user profile?

      There is an option to enable multi-user support in the settings if that is what you mean. Leave the box for it un-checked and multi-user support will remain disabled.

    nice. too bad my N10 is the device i have not rooted yet.

    what's the difference between this & superuser by chainsdd?

    • RB

      It's faster at gaining root access, and it's just more compatible with 4.2 at the moment.

      The reason devs like CM stick with Superuser instead of SuperSU, is because Superuser is open source, SuperSU is not.

      I would recommend SuperSU over Superuser. In my experiences it has been completely bug free and I cannot say the same about Superuser. @78f6b2075d74bc838e1e1f04a34c0d65:disqus is right, as far as I know the only reason CM sticks with Superuser it because they can have access to the source code.

        thanks for the info. now my next question: i just got my nexus 7. everything says to flash SuperSU after installing CWM. can i install cwm & then just get SuperSU from the play store?

    I can't confirm when it happened (I guess I'll do some research), but I wanted to let you guys know that the CyanogenMod superuser app had already accomplished this since before the SuperSu app update. I can confirm that is working marvelously on my Nexus 7.

    • Mack

      True but in my experiences SuperSU has been completely bug free when compared to Superuser. Cyanogenmod uses Superuser but it's not a CM developed app to my knowledge.

      • klatu

        I have used both and haven't had a problem with either. CM uses ChainsDD Superuser app. The point I was trying to make is that this article inaccurately reports SuperSU as being the first SU manager to bring support for multi-user when it was already accomplished by another SU manager before.

        • Mack

          Right, SuperSU definitely was not the first.

            Well, Chainfire had a version of SuperSu up on XDA with (partial) multi-user support less than a week after 4.2 came out. So, while this is an official update, Chainfire was the first one out with support - and the only, for nearly a month.
