Windows 10: Cannot get 2fa codes

Hello, I am contacting you on behalf of a friend whose computer has done a BIOs update and since then can no longer log in. Windows said security settings were changed and that the pin couldn’t be used anymore and he had to re-login to his Microsoft account. Once he puts in the correct password it says to check his email for the code. The codes are not being sent. The email is correct and it’s not in junk or being blocked. This has happened before. The email is *** Email address is removed for privacy ***. This needs to be resolved ASAP as this is his business computer and he cannot operate without it.

:)

 

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?

 

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?

 

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?
