Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Umesh kumar5
Good day to you and thank you for post in the Microsoft community.
We do apologize for the inconvenience caused to you due the above issue, to isolate the above issue
---- May I please verify the type of account you are using? Is it an M365 work/school account or a Microsoft/personal account like Hotmail/outlook.com? If your account is Microsoft personal account (outlook.com/live.com/Hotmail.com), please reply back to us, so we can involve personal account team for further assistance.
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, as you've posted in the business category and if you're using business account, these accounts are fully controlled by the school IT admins. 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.

If your account is Microsoft personal account (outlook.com/live.com/Hotmail.com), please reply back to us, so we can involve personal account team for further assistance.
At this time, your kind cooperation and understanding will be greatly appreciated.
Thank you very much for your precious time. Stay safe and healthy.
