Hello @Vijay Soni
Welcome to the Microsoft QnA and thank you for reaching out.
I understand that you are having trouble logging into the Azure portal.
To fix this issue first you will need to get an option to re-register your account in authenticator app for MFA. and then you can use authenticator app to login to Azure portal.
Admin has to perform below steps to reset your MFA so that you can re-register for authenticator app.
- Admin has to login to Azure portal and access Microsoft Entra ID.
- Once done they have to go to user's blade on the left.
- Click on the user account which is unable to login to Azure portal.
- Click on Authentication methods and click on “Require re-register multifactor authentication”.
- Now when you try to login to Azure services it will prompt you to register for MFA again.
If you are the only admin, this qualifies as a tenant lockout scenario. To resolve this, we need to engage the Data Protection team via a support ticket to unblock your access.
To proceed, I will need a few details from you. As this information contains Personally Identifiable Information (PII), please share the following details via private message:
- Contact phone number (add +Country code)
- Contact email address
- Global admin email address (affected account)
- Tenant Name
- Country
- Time Zone
- Tenant id/ Domain Name

- Last name
Please send me the detail via private message. Thanks
