Azure Sub locked out with a old number with no access to it.

Question

Azure Sub locked out with a old number with no access to it.

Alexandre E Capita 66

Unfortunately, the phone number currently registered for Multi-Factor Authentication (MFA) on the account is outdated, and I no longer have access to it. As a result, I am unable to complete the sign-in process or manage my subscription.

Key details:

Account Type: Azure DevSub (MCT)

Issue: Locked out due to MFA prompt on an old, inaccessible phone number

Action Needed: Reset MFA settings or remove the outdated phone number so I can reconfigure MFA with my current number or the Microsoft Authenticator app

Please let me know if you require any verification or identity confirmation steps to proceed. I would greatly appreciate your prompt support, as access to this subscription is critical to my ongoing training and development tasks.

Thank you for your attention to this matter

Hello Alexandre E Capita,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

If you are locked out due to MFA on an organizational account, only a global administrator or privileged account administrator can reset your MFA settings via Azure AD Portal or PowerShell.

The admin can reset your MFA status by: Navigating to Azure Active Directory > Users > Multi-Factor Authentication Finding the user and clicking “Reset MFA” This removes all registered MFA methods and forces setup at next sign-in.

Alternatively, the admin can use PowerShell commands like Reset-MfaOnUser from the MSOnline module.

Once reset, you can set up MFA again with your current phone or Authenticator app.

If you do not have access to an admin or co-administrator:

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:
