To reset your Multi-Factor Authentication (MFA) after changing your mobile device, you will need to follow specific steps based on your account's status:
- If you're the only global admin on the account: You should contact the Azure Data Protection team at +1 866-807-5850 for assistance.
- If your company doesn't have a global admin: You need to find the support phone number for your region and ask to be transferred to the Microsoft 365 Data Protection team for help with resetting your MFA.
- If you're part of the Microsoft AI Cloud Partner Program: Contact your organization's global admin for assistance in resetting your MFA.
- If you're a Cloud Solution Provider (CSP) Indirect reseller: Reach out to your Indirect provider for help in creating a new global admin or resetting your password.
If none of these scenarios apply or you need further assistance, you can find the appropriate contact at Support for Business Products.
Additionally, if you have set up security information, you can use it to reset your work or school password. This feature is only available if enabled by your global admin.
Make sure to verify any emails you receive regarding support requests to ensure they are legitimate, especially if you are concerned about phishing attempts.
