So my company decided to migrate office suite and email etc to Microsoft365. Whatever. But for 2FA login they decided to disable the option to choose "any authenticator" and force Microsoft Authenticator on the (private) phones of both employees and volunteers. Is there any valid reason why they would do this, like it's demonstrably safer? Or is this a battle I can pick to shield myself a little from MS?

Get a used /cheap phone or tablet, only turn it on or enable wifi when you need the app. Don't use it for anything else. I think that covers all the bases.

Declare yourself a member of The Church of Emacs and claim your religious rights are being violated.

While it’s not technically safer, MS does make it a lot easier to set policy’s where you check a box for MSAuth.

Since the config is less complex and easier, it’s demonstratably safer to implement it this way.

I managed to get around the MS auth app and am using aegis right now.

If you're in the US, that could very well get you fired in any "at will employment" state. It's shitty, fucked up, and should be illegal, but the legislators seem to represent wealthy corporations way more than they represent their human constituents (GOP especially).

You can just use FreeOTP

My company has the same policy

[–] metawish@lemmy.ml 5 points 6 months ago

Lots of great conversation here, I also work somewhere where this is required. If I didn't need my phone for access to chat, I just wouldn't use it for work. Alternatively, my phone has a work profile so I use that for any work related or non-FOSS apps. My IT guy even approved of my methods and said do the minimum and never more with tech.

If MS Authenticator still works with totp urls just like any other authenticator then you can just use some open source authenticator. Some password managers even have one built it.

We let anyone use any authentication app. The Microsoft one is the best one. I'm pushing to make us exclusive because I'm sick of the IT support guys trying to support a dozen apps. You don't have to use your Microsoft account provided to use the app or back up your credentials.

I’m pushing to make us exclusive because I’m sick of the IT support guys trying to support a dozen apps.

While I understand this... Why not just refuse to support and NOT remove the capability for all those who don't need support and work just fine with their own? It's not like TOTP isn't a solved problem at this point.

Eg. "we only support MS auth, If you choose to use your own you will not receive any company support."

[–] Crashumbc@lemmy.world 5 points 5 months ago (2 children)

Because that shit only works in fantasy land. If you can use it, employees WILL expect support and will repeatedly raise hell if they don't get it. Is a losing battle.

[–] Username@feddit.de 4 points 5 months ago

The option to use TOTP is already well hidden. It's not like someone who does not know what he is looking for and uses an Authenticator already will accidentally select it.

I used bluestack to emulate android and us MS Auth when I had no choice.

It's a waste of space, but it doesn't go on your phone at least

[–] fouloleron@lemmy.world 5 points 6 months ago

Authentication methods in Entra ID (which is presumably what we are talking about as the identity provider) include Microsoft Authenticator and software otp.

Authenticator is push authentication, as described elsewhere here. If for some reason you're not getting push notifications, you can use an OTP code instead, but this still requires that you have push authentication configured in Microsoft Authenticator.

You can only use Software OTP in other applications if your administrator has explicitly allowed use of Software OTP as an authentication method, and also excluded you from being required to use Authenticatior - otherwise Authenticatior would always 'win' as choice of mechanisms because it is more secure.

Several states in the USA require that employees who are made to use their personal phone for business purposes be compensated. The enforcement method and process for requesting same is naturally very obscure.

Grab the shelter app from f Droid, add the Play store in shelter, move over to the work side Play store and install the authenticator.

Pause your work apps except for when you need to use the authenticator.

Prosper???

What is your concern about installing MS Authenticator.

I mean I can understand the principle of being forced to install anything on your phone.

But just stepping into the practical for a second: What do you worry will happen by installing this app to your phone?

[–] Martin@lemmy.ml 4 points 6 months ago (3 children)

I'm not concerned per se and I definitely applaud the MFA requirement. I mean I hate MS and don't like apps I don't need, and I don't trust them, but as others pointed out this would mostly just be whiny. That's why I asked for reasons why restricting users to MS Authenticator would be preferable. If it's more secure or technically way easier and thus cheaper to maintain then fine, I'll find an acceptable way to comply. If not, then it's them who are whiny and I'd rather make the case to let us use whatever authenticator we already have installed.

reasons why restricting users to MS Authenticator would be preferable

As a security professional:

  1. Under most situations, it is equally as good as any other 2FA app.
  2. Within the Microsoft ecosystem, it provides additional security features above and beyond simple 2FA.

If your workplace is leaning heavily on the Microsoft ecosystem, especially their cloud offerings like Azure, then restricting employees to the Microsoft app is a no-brainer, and actually quite reasonable.

For example, if they happen to have a hybrid domain with an on-prem domain controller syncing with Azure (forgive me for using obsolete terms, I’m a greybeard), then they can control all access to all company assets, including 2FA. If an employee leaves the company, they can also disable the Microsoft app at a moment’s notice by disabling the employee’s Microsoft account. Because everything is hooked into Azure, it sends push notifications down to all company assets - like the Microsoft 2FA app - to unhook all of the company’s credentials and prevent employee access after the fact.

You cannot do this with other 2FA apps.

But MS Authenticator isn’t a normal 6-digit Authenticator; it scans your Face ID (or finger print) and in many cases (like my work) it can be support password less accounts (relying only on something you have and something you are).

And in regard to your point that you don’t want to install apps you don’t need, it sounds like you do in fact need this app.

🤷‍♀️

Your employer might use MS Authenticator but still let you do call or SMS 2FA. If you use a VOIP number, it won't be vulnerable to SIM card swapping attacks.

You have the right not to use your personal hardware for work, and the employer must provide the necessary equipment to accomplish your job.

Ask if you could get a hardware token (ie: Yubikey Security Key) instead of using Microsoft Authenticator to fulfill the security requirements. It's low cost and doesn't require a subscription unlike a cellphone plan.

At what point can you tax deduct your phone as a business expense?

[–] Reverendender@sh.itjust.works 4 points 6 months ago (9 children)

And here I am wishing they would come out with an authenticator watch app, so I didn't have to do all the work of taking my phone out of my pocket and swiping a few times.

[–] bandwidthcrisis@lemmy.world 4 points 6 months ago

What's needed is an online 2fa service that just takes a username and copies the code to the clipboard.

/s before I get any replies.
