Hello Iqra Hussan
Good day! Thank you for posting to Microsoft Community. We are happy to assist you.
Based on your description, you're having trouble with accessing your account due to MFA authentication. In this scenario, the best way is to reset your MFA option, so that you can re-configure it when you login the next time.
I understand that you're having trouble accessing your account. Since your query is regarding the Microsoft Authenticator app, we have a separate community team, so it is recommended to post through Microsoft Authenticator - Microsoft Q&A so that a support agent from that team can verify and provide you with the necessary information.
Alternatively- if you're using a Business/ work account, these accounts are fully controlled by the company. You can contact your M365/IT administrator so they can reset MFA and remove the previous authenticator app sessions or add another authentication method for you through the Azure admin portal, such as phone/SMS, so you have more options for accessing your account. More information on how to add them here. Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
If you need guidance on how to find your admin, see How do I find my Microsoft 365 admin? - Microsoft Support
**If your account is Microsoft personal account (outlook.com/live.com/Hotmail.com):**please simply reply back to me, so I can engage Microsoft personal account's team for further assistance.
If you are the admin only and not able to access your account, you need to contact Data protection team because we are from community team and we are not authorized to reset any user/admin account. Data Protection Team is the only support team to check and reset account. To find contact number of Data Protection team, please check Global Customer Service phone numbers - Microsoft Support.
Apologies for redirecting you to different community , As we are community team, we have limited permissions in handling the current scenario you've brought to our attention.
Thank you in advance for your understanding. Your patience and cooperation will be greatly appreciated. I hope for all the best!
Sincerely,
