Wait, can you eli5 why multifactor authentication (MFA) (and maybe also 2-factor authentication apps) is “fuck off” levels?

Is it privacy concerns or something bigger like more points of failure for overall security? Or smaller like not every one has/wants a smart phone?

If I read it correctly the "fuck off" level refers to some proprietary app for the selected login. The other two are standard code app and yubikey.

This is also how I read the meme. Codes are fine, tokens are fine. Your proprietary spyware app is NOT fine (Microsoft) and I hope you get fucked.

Microsoft login works just fine with any TOTP app, like Aegis. They just heavily push you toward their app.

Unless your company doesn't know wtf they're doing and it just doesn't work.

[-] mvmike@lemmy.ml 1 points 4 months ago

Depends on how it's configured by the company. I've faced in the past the situation of having to login with the company email to be able to use the MFA with a propietary app, which meant I needed to enroll into the BYOD policy and it includes remote device management.

Ended up installing an emulator in the work laptop just for that purpose and left the company shortly after.

It's usually duo. I hate duo so much

MS is fine, your average bank or broker institution though... when it's not SMS, chances are it's an "in-house" solution

[-] HeartyBeast@kbin.social 4 points 4 months ago

You talking about MS authenticator? In what way is that proprietary or spyware?

[-] mark3748@sh.itjust.works 2 points 4 months ago

They offer other options for Microsoft accounts. Using it as a normal TOTP app is the same as any other Authenticator app.

It’s most likely the number matching requirement that the other person doesn’t like, or their employer has a policy that’s annoying.

Not the OP, but I have to use the stupid Microsoft authenticator for work, and half the time it's hibernated and doesn't wake up when prompted, and when I manually open the "verify login" tab, it spits out an OTP but doesn't recheck for that 2 digit number number I have to enter.

And the login prompt on Windows doesn't have a "resend" button, I can merely click "I don't have access to the authenticator app", and then it offers me the option to... Enter a manual code (courtesy of the authenticator app) or use the authenticator app. Dumb as fuck.

If then I opt for the authenticator app instead of the override code, there's a ~30% chance the app will not accept the new number because it's still expecting the former one, if you're too quick to enter it.

Piece of garbage.

Yeah, I've seen that prompt at least 50 times by now. There's almost always a button to use a different authenticator app, which shifts the code to be TOTP compliant.

I don't think I've ever seen that button not be there.

To be fair, the MS authenticator app is also useful as a totp app, so it's not all bad. I mean, I don't use it, but it's not all bad.

If your company (assuming this is for ms365) can also enable FIDO2, so yubikeys are also possible, but they're not enabled by default, so your 365 admin needs to go press a button to allow that for you. MS even supports passkey for passwordless login. But again, not enabled by default. Fun fact: Windows 10/11 also support all of this but if you're on an active directory domain.... You guessed it, it's not enabled by default.

To their credit, Microsoft has made some pretty significant strides in account security in recent years. It's pretty impressive; though requiring a TPM for desktop Windows (especially the "home" versions) still makes me raise an eyebrow. Overall it should help with security.... But a hard requirement? Okay Microsoft. If you say so.
