I can guarantee this will be a hilarious shitstorm of false positives wasting IT departments' time, because their detection of it is massively flawed.

At least once a month my - completely stock, and un-rooted - phone tells me I can't use Outlook/Teams because of root. Every time, a reboot is required to resolve this. One one occasion, TWO reboots.

Ignoring whatever reason Microsoft think they're blocking this for, it's going to regularly block regular users, who are not going to stand for it.

    Why would you use microsoft Authenticator anyway? There are other options

    I don't really mind using shit software on work devices. Yes it's slow and inefficient, I spent half an hour today on Windows doing what would be a very short command on Linux. Fuck it, get paid the same. I just use Linux at home in my own time.

    I'll point out better software exists. If I don't get support in changing it or allowed to change it, fuck it. It's on them at that point.

    You can use other authenticators. I use ente auth for my microsoft account

    I can't. The authenticator for my job was set up on my work device by my IT department.

    Sucks to have that. Have you tried asking IT if you could use a different one?

    The main problem as I see it is if I have to download authenticator onto my personal device because something has happened to my work device. That's the only way I could see this being a problem since I use Graphene OS on my personal phone. Even then I would probably just use the authenticator on my work computer rather than going to that trouble.

    Only if the company supports OTP methods for Entra login (logging in to M365 account).

    But I'd say most don't anymore, as there has been a push towards Microsoft Authenticators push-method for a while (where the website/app shows a number and you have to type it in to the authenticator), as it is a slightly safer method than OTP, and can be used passwordless.

    It also made people ready for passkeys, as the authenticator supports easy activation off passkey on accounts that are saved with push-method (you pretty much just click a button in the app), and authenticator is easy to set up on the admin side if you require device bound and attestation for passkey.

    You don't need it for work. You can use any authenticator.

    It depends…. Your company IT department can choose what types of 2FA are available to use and Microsoft Authenticator is separate from OTP and other methods, and it is possible to restrict them.

    That’s also yet another reason why I force the issue of a company phone as part of my equipment to do my job.

    Work isn't an excuse unless your work is trying to cut corners by having you use your personal phone instead of providing a work one. In which case they deserve to be taught this lesson for being cheap as fuck.

    Your IT should be issuing you a phone handled by MDM, which should be locked down and not allow you to use a rooted or jailbroken device anyway.

    Nope, the Microsoft authenticator is slightly different, and other authenticators won't work. I just went through this with my IT dep. Microsoft authenticator will sometimes pop the numbers up on the computer and make you enter it in the app, not the other way around.

    Some organizations require authenticator; they don't just use it for MFA codes, it's goes deeper than that.

    Also, most large enterprise fall for the stupid Microsoft trap. They buy enterpise licensing in bulk (E3, E5, whatever) and bosses who have no brains will say "well, let's use more microsoft products since they're 'free'". The trap is that, yes, your enterprise license agreement includes entitlements to a lot of their stuff, but they nickle and dime you on stupid shit like the storage so you can keep the logging and telemetry data you typically need for security, troubleshooting and some audit requirements.

    I can't imagine ever using any of their shit beyond Office products. Their security software is crap compared to most offerings, they still seem to think that networks are bad so we should do as little as possible about them. Azure is just a completely uncontrollable money drain (by design) that is damn near impossible to secure properly once you give developers enough access to actually do their jobs.

    I've been working in security for a long time now and they continue to be such a fucking liability and drain on money at every turn. If I ran the zoo, I would switch the entire enteprise to Linux and find just about any other collaboration suite to use.

    Fuck Excel and fuck you if all you do with it is make lists. Fuck powerpoint and fuck every boss who is too dumb to read and only can accept information when it is spoon fed to them in a deck. Word is OK, but nobody reads anymore so what's the point?

    I had to use it for my work. They required MS authenticator. I think it's bullshit and tried to export my 2fa to bitwarden. I couldn't. And to add another 2fa .method I need to call support so I gave it up

    They don't let you use https://mysignins.microsoft.com/ to replace/add MFA methods? That site was very useful at my last employer, as I was switching phones often.

    Probably. I suppose that I was lucky that I could manage these things myself. As we had only one local IT FTE, and I wouldn't have known who to contact beyond that single resource. And might have hated life if I had needed someone else to manage this for me.

    Yup, I use Aegis, and found a strange little trick with Bitwarden Authenticator where I can import them into the main app (the Vaultwarden server). I know keeping all my power in one place defeats the purpose of 2FA but you know, I trust Vaultwarden, and myself to keep it secure, implicitly.

    This change is really more about enterprise use cases. If you take DLP seriously you need to make sure the integrity of the controls on work provided devices are intact. Authenticator isn't managed by intune since users could use it for many things.

    Nothing stops someone taking a photo of another screen. It's not a panacea. It's just one more hurdle.

    They're not mutually exclusive. Yubikey is great for passkeys and Ente Auth is great for 2FA.

    Yes, I'm aware, but if both your passkey and your OTA codes are on the same device, it's not really two-factor authentication anymore, is it?

    Your passwords sit in your password manager, the Yubikey is your 2FA.

    Depending on the service you’re using they may allow you to use WebAuthn to authenticate your account passwordless so all you would need is your Email/Username + Authentication device, however not all services support this.

    How does the tool actually check for this?

    Does it just use the Play Integrety API, or does it use some kind of other attestation check?

    The need for full root privilege has fallen by the wayside assuming you can trust the OS running on the device. I dont hate this change if I can run a custom ROM that will report that the user does not have root privilege and that the OS has not been modified since boot.

    Get some cheap alternative and put the authenticator on that phone and say that is your main phone.

    I wont use my personal phone for anything work related except authentication. Since it sits in its own little jail, it's fine.

    I work all over the world and remote in. I have no other work related devices or equipment.

    I look at it as a key card from the old days when I had to go into a building. I think that is a pretty trivial use case and doesn't need them to provide a phone, and in fact I absolutely would not want a device owned by anyone else that I carried around. That is FAR worse.

    That said, this change sucks as I will now need to get around this bullshit.

    I disagree.

    In fact, there is a strong argument to be made that storing your TOTP secrets in the same place as your passwords is bad practice.

    You now have a single point of failure that if exploited, could grant an attacker total access to all your accounts.

    Google is doing their best to strangle those too, by only releasing their source code when a new major Android release comes out. Custom ROM developers then have to rebase and integrate several months of commits all at once, with nowhere near enough time or resources to actually vet more than a tiny fraction of the changes.

    Not everyone. Depending where you live there's no devices available that are compatible with secure custom ROMs (you might be able to deGoogle, but that's different from being secure).

    Your security doesn't just depend on what flavour of AOSP you decide to use. I'm assuming you're referring to GrapheneOS, which is only compatible with Pixel devices. Your threat model is also highly relevant. Depending on who you are and what you do, you can be secure on say LineageOS, which will run on a large variety of devices.
