Support cannot be contacted or tickets managed from here.

To get the authenticator/MFA reset and speak with someone by phone, use one of these options based on the scenarios in the references:

1. If this is a work or school (Entra ID / Microsoft 365 business) account and you are the only admin:
   • Call Microsoft’s Global Customer Service using the regional number listed under Customer service phone numbers - Microsoft Support.
   • When the IVR asks what the problem is, answer along the lines of:
     • Problem: “Authenticator”
     • Product: “Office 365 for business”
     • Account type: “For companies”
     • Are you an administrator?: “Yes”
     • Any other admins?: “No”
     • Do you need a service request?: “Yes – I need to create a ticket and speak with the Data Protection team about resetting my MFA/authenticator.”
   • The Data Protection team has the tools and processes to verify identity and reset the admin’s MFA when locked out.
2. If there are other global admins in the tenant:
   • Ask another global admin to sign in to the Microsoft Entra admin center and use Require re-register multifactor authentication on the affected account so MFA methods can be set up again.
3. If support is hard to reach as an admin of a business tenant:
   • As a workaround, create a temporary trial Microsoft 365 tenant (as described in the references) and, from that new tenant’s admin center, open a support ticket explicitly stating that access is lost to a different tenant where you are the admin and MFA must be reset. Be prepared to verify identity and admin rights.

For personal Microsoft accounts (Outlook.com, Hotmail, etc.), use the standard account recovery and verification-code troubleshooting flows; support agents cannot directly reset MFA or send codes and will direct through the online recovery process.
