How do I turn off Microsoft Authenticator?

Does one of these settings disable the authenticator app?

We're in the same position as most of you. We don't want the authenticator app. MFA is working just fine for us. Being forced to use that will be a real PITA. We have a lot of non-tech savvy users. Changing anything requires a lot of hand-holding. And our users are spread out over 4 counties so not all in the same building either (~325 users).

I've already gone through the process of seting up the authenticator app when the prompt no longer allowed me to click on "Not now" and it was NOT very user friendly. I've turned it off but now I'm back to answering the same prompt as before. I'm wondering how long "Not now" will be available and I have to go through the same process of setting up the authenticator app. ARGH!

I can't find any such security tab as Mario mentioned.

I've disabled it several times - but the next time I login I get forced to "Improve your sign-ins". I really wish Microsoft would quit trying to force their crappy products down my throat. I value my choice. I don't want Edge, Cortana, Bing or their stupid authenticator app.

You have to go to Multi-Factor Authentication in Users menu. Then Click "Service Settings". It doesn't look like a link because Microsoft is stupid and doesn't know how to make it look like a link. Then you'll see the settings you want to disable. Keep in mind, this might take 30 minutes or so for Mircosoft to replicate across all of it's servers. Pictures below

We have the same issue now and it's really frustrating, since I can not simply and DO NOT WANT to install an app on my phone. I had MFA active via SMS and exactly this happens now to us aswell. I would turn off MFA but simply can't because 1) I need to install an app, that I am not willing/easily able to install. 2) it would leave my account less secure, which I would need to get approved - and that won't happen (and would be wrong).
