How to get rid of Microsoft Authenticator? I have Office 365 subscription and it works well. However, I got Microsoft Authenticator app installed on my Samsung Galaxy and it got my Outlook account added there. I have no idea how that happened since I did not add it. 

I've read the instructions from https://support.microsoft.com/en-us/help/4026727/microsoft-account-how-to-use-the-microsoft-authenticator-app but the instructions are complicated. I don't need this Authenticator, so I want to get rid of it.

How can I get rid of it and keep my Microsoft account?
You must both delete the app from your old device and tell Microsoft to forget the old device and unregister it from your account.

•   To remove the app from a device using a personal Microsoft account. Go to the two-step verification area of your Account Security page and choose to turn off verification for your old device.

Then you can uninstall the app just like any other app
