I’m lucky my banking app works (GrapheneOS), as it’s now requiring 2FA with the app anytime I login on the browser. Can’t use an actually secure form like TOTP. At least they now allow passwords over 8 characters (yes, serious).

    Magisk plus DenyList luckily works for my banks. Couldn’t imagine not having a rooted phone.

        What are the security issues? Rooted just means the potential to give trusted apps root access. Of course, if you give an app root access that you trust but is then abusing that trust and being malicious, yes it’s a security issue. But if you don’t do that, the simple fact of having a rooted phone should have no security change in any way. (Ok, except for potential bugs in Magisk/su or whatever)

          https://www.reddit.com/r/GrapheneOS/comments/13264di/comment/ji54e19/?utm_source=share&utm_medium=mweb3x&utm_name=mweb3xcss&utm_term=1&utm_content=share_button

          If you have the UI layer able to grant root access, it has root access itself and is not sandboxed. If the UI layer can grant it, an attacker gaining slight control over it has root access. An accessibility service trivially has root access. A keyboard can probably get root access, and so on. Instead of a tiny little portion of the OS having root access, a massive portion of it does.

          In the verified boot threat model, an attacker controls persistent state. If you have persistent root access as a possibility then verified boot doesn’t work since persistent state is entirely trusted.

          A userdebug build of AOSP or GrapheneOS has a su binary and an adb root command providing root access via the Android Debug Bridge via physical access using USB. This does still significantly reduce security, particularly since ADB has a network mode that can be enabled. Most of the security model is still intact. This is not what people are referring to when they talk about rooting on Android, they are referring to granting root access to apps via the UI not using it via a shell.

            I’m pretty sure whoever wrote that was talking out their ass. The fuck is “UI layer” on Android, or rather, what does it have to do with it xD

              The actual Magisk prompt that ask you if you want to give root to such app. This UI layer.

              Although, i suppose it could be countered by explicitly refusing all requests or enabling a biometric confirmation

                But granting root is not done by “the UI layer”, “the UI layer” is not running with root. There is no such thing as “the UI layer” as a separate entity, an app can have a UI layer as part of its architecture, but the UI is not running on its own. Just because Magisk shows you a UI for you to grant/deny a root request, that doesn’t make it insecure. Nothing is able to interact with this prompt except the Android kernel/libraries itself and Magisk.

                Only if you added an application as accessibility tool (or give it root) can it interact with anything within the UI. An app with a UI is generally not much different than an app on the command line.

          The whole issue revolves around the fact Google is presuming a device is compromised or being used for illicit shit simply because root access is possible. If they put in effort to detect/prevent the actual problems they’re concerned about, this wouldn’t be as big a deal. This broad punishment for simply having root access is lazy and ridiculous.

          It’s like if Windows apps just stopped working if they detected a local admin account. It’s patently absurd to assume the ability to access anything means the device is inherently “unsafe”.

        GrapheneOS is made by diva developers who frankly should not be trusted. “We only allow Google phones to run our OS!” as if they don’t have a backroom deal with Google.

            Pure wild speculation if I’m honest, however I’d be more surprised if I was completely wrong. It’s always seemed sketchy the way Google have basically said “Use our phone, it’s more secure!” with their Nexus and Pixel phones - this was long after the time Google stopped not being evil. At best, the security problems have simply changed manufacturer. Also, Google have a history of undermining development of circumvention, eg hiring the developer of MicroG and forcing him to stop development as a term in his contract.

            The diva part is widely known, GrapheneOS developers don’t play nice with the rest of the custom development community. So, while I can’t substantiate any actual deal between them and Google, it’s the perfect recipe.

        Can you compile your own OS from source for an iPhone and install it yourself? I don’t think so.

        I have done that with my non-rooted android, and I can do anything I want with my phones through the powers of open source software.

        Rooting is unnecessary now and that’s a good thing.

            Well you can, and there is no punishment, so you should be happy.

            I imagine you probably think “punishment” is that some bank won’t let you use their app on a rooted phone. That is not a punishment, that’s the bank implementing the security that they deem necessary for access to their software, and is likely part of a license agreement that you agreed to by using it. You have no default entitlement to have free use of the software that anyone else produces unless the software developer’s license states that you do.

            Actual punishment would be if your phone gets bricked by the OEM for rooting it, or government authorities fine or arrest you for rooting.

          You can’t do that without unlocking the bootloader, and that alone will trip “root detection” (Play Integrity).

          Some apps take it further and won’t run if you enable Developer Options! (Or have any number of “hacking apps” installed, such as autotap apps that don’t even need root.)

            Yes, I am aware of how it works. Unlocking the bootloader is not the same as rooting, and all my apps work just fine.

              If they work with an unlocked bootloader then they would almost certainly also work fully rooted, with the advantages that brings (such as actual working app+data backups, limiting max battery charge, better automation possibilities with apps like Tasker, etc)

              I’d much rather switch banks than give up rooting my phone.

            You are being downvoted because you’re factually wrong. While Android (especially on Samsung devices) had been getting more locked down over the years, even unrooted it has way more freedom than an iPhone. For instance, you can install any number of APKs, without jumping through any hoops.

              For now. Google’s recent patterns would seem to indicate the future trajectory of Android to become even more hobbled.

              I doubt it will ever be as closed as iPhone but there’s a point where the door is technically still open, just not in a way that really means much.
