Microsoft Authenticator is about to wipe work accounts from jailbroken/rooted phones automatically 👏.

Wow. So a LOT of you folks are not happy.
The good news is your org can still allow you to use passkeys and other Authenticator apps.
@merill lol!

@merill You just told a bunch of power users they either need to either relinquish control of their personal devices or start carrying a second device. Why did you think they'd be anything other than unhappy?
-
@fluffykittycat @merill It's kind of a grey area. They are right that open bootloaders are a security issue but then also you can relock it on some devices.
In any case I don't think I would use the Microsoft Authentication app anyway unless I have to.@thaodan @fluffykittycat @merill Why?
The keys and such associated with the authenticator app should be in a TPM. Something the bootloader can't touch. It can't get the private key to then send it to whoever.
The bootloader could attack in other ways and get the info you're accessing once logged in, but I don't think it can mess about or bypass the actual security mechanism.
I think they're trying to sell bullshit here so the ignorant support them as they lock us all down.

@thaodan @fluffykittycat @merill On phones without a TPM that's obviously not the case, but there are fewer and fewer of those and will be fewer still.

@merill what exactly is the threat model that makes a rooted device risky for an authenticator app?

@merill The orgs won't allow employees to use anything else, and you know it. Sadly you are not the first to require non rooted devices, but it is still another step back for freedom and privacy. Let us use our general computing pocket device as we wish. Or at least allow orgs to toggle the need for this. Though most will just enable it without question.

@merill tell that to my org that only allows the authenticator app.

@crazyeddie @fluffykittycat @merill The bootloader itself isn't the concern but the kernel and what is started afterwards.
It is a factor even if they only use it as an excuse. Most phones don't have a TPM but an ARM trustzone which can run a software TPM. The problem is that modifying or writing isn't possible low level only over the OS or vendor API's provided. -

@merill I wonder who of the people complaining here do…
1. … own a rooted / jailbroken phone
2. … have Microsoft Authenticator installed on this phone
3. … do use MS Authenticator in combination with an Azure Active Directory account. -

@crazyeddie @thaodan @merill unlocked bootloaders are a moral imperitive. Not to mention all the ewaste created by locked devices not being repurporsable
-
Soo instead of just rooting a phone one needs now to also deploy 38473894 shady scripts and workarounds to hide it from Microsoft Authenticator?
Congratulation on improving security (NOT).
-
And make your employer pay for it. I got my work phone when I refused to put a similarly shitty 2FA app onto my personal one.
I just said I've a PinePhone with Postmarket OS and I'm not going to buy a new one just for that. + I asked if they'd cover damages for any data deleted because of someone hitting the "wipe phone" button in the MDM that would have come with it accidentally (or on purpose).
The phone was cheaper for them than continuing the discussion btw
-
@merill I'm gonna go out on a limb here and say that users that jailbreak their own private device wouldn't use MS Authenticator, and on company devices jailbreak wasn't allowed anyway.
@silhouette @merill people are expected to put this on their personal devices
-
@merill TIL people actually use the MS authenticator
@Longplay_Games @merill not by choice
-
@silhouette @merill people are expected to put this on their personal devices
@fluffykittycat @merill ah, the famous "use your own private resources for the benefit of the company".

@fluffykittycat @merill @crazyeddie Context? Nobody in the thread said that devices where users can't unlock bootloaders are a good thing.
Users should just be able to relock it. Locking bootloaders doesn't block flashing it just ensures that only code signing with the owner of the keys in the bootloader can be used, the owner of these keys can be the user. -

Sucks.

@merill what the fuck. You all really want to kill open computing, don't you.

@crazyeddie @thaodan @merill yeah, locked bootloaders imply the person who purchased it doesn't get full ownership rights over it
