  Anything closed source could have backdoors. Trust no one.

    As per their FAQ:

    Permission to access your location

    Q: I got a prompt asking me to grant permission for the app to access my location. Why am I seeing this?

    A: You will see a prompt from the Authenticator app asking for access to your location if your IT admin has created a policy requiring you to share your GPS location before you are allowed to access specific resources. You’ll need to share your location once every hour to ensure you are still within a country where you are allowed to access the resource.

      And? I don’t give a shit what the admins of my network want. It’s DFA – they don’t deserve to know that. Ergo, I don’t use the MS app. They can kiss my ass.

        It’s a security / compliance policy. There is a very high chance your company has not even enabled it, have not seen anyone using it.

        As I see it, you would and could use it only if you force MS Authenticator notification as the only MFA method and it is important in which country MFA prompt originates. Usually it is IP based block / whitelist which checks IP from which login originates which seems like a much more useful info, then you can also allow any MFA method.

        You can always deny permissions to apps.

  That depends. More of the popular ones don’t encrypt the secret keys, they can just be read out with root access or even with the use of ADB (the pull command), not even speaking about reading the memory contents while booted to a recovery.
  Some even uploads the keys to a cloud service for convenience, and they consider it a feature.

    Sounds more like a bad design than purposefully left backdoors. Very few devices are rooted and usually you cannot get root without fully wiping your device in process. As for cloud upload, that indeed is convenient for most regular users. I prefer encrypted offline backup like Aegis does, but you need to think about regular folk if they would loose or wipe their device.

      It’s not bad design, it’s definitely intentional, however I agree that it’s probably not for having backdoors, but for convenience. Average people forget their passwords all the time, and with encryption that level of carelessness is fatal to your data if they have not saved it somewhere, which they probably didn’t do.

      I’m pretty sure the system is not flawless. Probably it’s harder to find an exploit in the OS than it was years ago, but I would be surprised if it would be really rare. Also, I think a considerable amount of people use the cheapest phones of no name brands (even if not in your country), or even just tablets that haven’t received updates for years and are slow but “good for use at home”. I have one at home that I rarely use. Bootloader cannot be unlocked, but there’s a couple of exploits available for one off commands and such.
