Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Dear Aaron Fite,
I understand you are having issues with Microsoft Authenticator. Regarding the phone number for global support, for a full list of regional numbers, you can also visit this official page: Customer service phone numbers - Microsoft Support
As a forum member like you, I don't have access to internal Microsoft systems or special escalation channels. The suggestions I provided are based on what I have observed from many similar cases I have seen in the forum community.
Moreover, according to my research, the available support options depend on the type of account you're using:
1/ If you are using a personal Microsoft account (Outlook.com, Hotmail.com, Live.com, MSN) and can't access Microsoft Authenticator, I recommend you try the Microsoft sign-in helper tool. For more information, please refer to this article: I can't sign in to my Microsoft account
2/ If you are using a Work or School account, please get in touch with your organization's IT administrator. They can reset your Microsoft Authenticator registration, update your MFA settings, or provide an alternative sign-in method if you are locked out. For reference: How do I find my Microsoft 365 admin?
For more information and instructions, please ask the organization's IT Admin to follow the Microsoft Official Guide here: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
If you are using a work or school account and you are the only Global Administrator in the organization, I recommend contacting Microsoft Support, as only Microsoft Support's Data Protection team can assist with account ownership verification and administrator recovery. For more information and instructions, you can refer to this: Locked out of Admin Account because it does have a microsoft Authenitcator access
Thank you for your patience and understanding. If you have any questions or are stuck on any steps, please feel free to reach out. I'm looking forward to your update
