I need help with logging into Microsoft 365 without Authenticator

Question

Hi, I cannot log into Microsoft 365 Account for business, it keeps asking me for Authenticator codes. I have a password and I know it, and I have put my phone number in Overview. I deleted Authenticator on old phone, and I tried to add it on a new phone, but it asks me again for a code from Authenticator. I cannot find QR code on Microsoft account to login to Authenticator app, nor can I access Security info on Microsoft account - it goes in vicious circle, always asking for Authenticator codes... I marked flagging option, but I didn't receive an email on Organization email.

I see that a lot of people had similar issues but answers on how to access it have been deleted for some reasons. So, if someone can help me change the method for signing in, or logging in some other way i would be grateful.
