Hello @hoa.van

Based on your description, it appears that you are unable to log into the Azure Portal due to an changed you MFA device.

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

Time Zone

Please send me the detail via private message.

We can then connect offline to discuss further and assist you in resolving this issue.
