Business account asks for authenticator app
I have my own business and I want to create a business account for my company with Microsoft. Now I have done that, in my website I had to incorporate something, all succeeded. Then suddenly I couldn't log in, had to sign in to 365. Okay, I was going to do that. Then suddenly I had to log in via the Authenticator app, but I never created that. The app is not set up and if you want to do that, it asks for a QR code. You can only get this if you are logged into your account. But.... I can't log in because then it asks for authentication through the authenticator app, which so I have to set up first. Currently, there is no way I can get into my Microsoft accounts. How can I 'just' log in without being required to use that authenticator app.
