Hello @Ajay Dudhedia

Thank you for posting your query on Microsoft Q&A.

Based on your description, it appears that you are unable to log into the Azure Portal due to an incomplete MFA process. Since the device registered for second-factor authentication are not getting any MFA prompts, you are unable to complete the authentication.

In such scenarios, another Global Administrator can help to re-register MFA on a new mobile device. However, since you mentioned that you are the only Global Admin in the tenant, 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)

Country

TimeZone

Please send me the detail via private message.
