Hello,
Greetings! Thank you for reaching out to this forum. I'm Ravi, just like you, a fellow Microsoft user and I'm here to help you with your question today.
Could you please try to use any alternate verification method like email ? If you able to use email option, please try to disable MFA temporarily.
You will have option like "other ways to sign" or "I don't have access to my Microsoft Authenticator App"
Incase if you wish to modify the MFA option, kindly try to login into the security page,
- Go to the Security basics page and sign in with your Microsoft account. https://account.microsoft.com/security
- Select More security options.
- Under Two-step verification, choose Set up two-step verification to turn it on, or choose Turn off two-step verification to turn it off.
- Follow the instructions.
