Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Zemirah Reyna,
Good day! Thank you for posting to Microsoft Community.
I am sorry not able to sign in to your account. I do understand your query here, but as you are using school account, I sincerely recommend you contact your college IT admin to reset your multifactor authentication session from their end in the Microsoft 365 admin center, to be able to add your account to your authenticator app in new phone and sign in to your account. It's important to note that since we have limited resource and privileges as Microsoft Customer Support, we are not allowed to examine institutional end users account authentication scenario. If the accounts are educational or organization-managed, only the owner or IT staff of that school or organization has the right to manage accounts, including resetting the account multi-factor authentication, allowing account to change authentication methods and changing phone number for authentication method. Therefore, I sincerely recommend you reaching out to your school IT admin or the person who is in charge of managing Microsoft 365 admin center of the school. The admin can refer to this article, to be able to reset the multifactor authentication session of your account in the Microsoft Entra ID admin center, see Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID | Microsoft Learn
Thank you for your precious time and kind understanding.Have a nice day.Sincerely,Libeamlak | Microsoft Community Moderator
