Windows 10: Locked out of FB account because 2FA sends code to authentication app I never set up

Hello all, I really hope someone can help me.I have read several other similar threads, but none of the fixes there worked for me.I am logged into my FB account on my android phone with no issues.I was logged out of it on my laptop, and when trying to log back in, it says i have 2 factor authentication set up, and asks to enter the code from my authentication app, which i do not have set up.It used to have an option to either SMS the code to your phone or show it in your mobile account when logged in, now this is the only option showing and so i cannot log in on my computer. When I click

Grandparents Account Locked 2FA set to Landline

Good morning,

My grandparents have locked the Microsoft account and are unable to receive the 2FA code. Apparently they got confused when setting 2FA and entered their landline which can't receive text messages. I'm not seeing any other option to send the code to their email for verification.

Account recovery seems to be denied because 2FA was enabled. What next steps can we take?

 

GMAIL 2FA Authentication Question

Thanks for replying. Apologies, but I was reluctant to use the link that you supplied. I do not want to remove text and call. I do not want text or call to be the default options which it is now after I reset my password. I want to add Use Backup Codes to the main options as well as the GOOGLE Authenticator option. And I do not see that now. Only this:

And when I click on 2 Step Verification it shows this:

Which is why I am still mulling over the option to remove my phone number and disable 2FA and start over. I'm hoping if I do that and do not enter my phone number first I will get the options back of using the Backup Codes and the Authenticator app and then add my phone number and hopefully this time the phone number will not be the default option. What do you think?

 

MS Authenticator doesn't transfer 2FA codes

I have two phones where I want to use 2FA codes on both phones and after installing the Authenticator on the second phone I used the Recovery option to add the same account but none of the 2FA codes moved to the 2nd phone. What am I doing wrong?
