Answer 1

I’m trying to sign into my school account through the authenticator app and nothing is working. It doesn’t generate a code or I can’t approve a request. I deleted the account and added it back and I’m still going through the same issue. When I try to sign in on the app it said that I didn’t have access to my account.

Answer 2

Hello @Kayque Emanuel

Welcome to Q&A forum! 

In your case, since you are using a university account, your account is managed directly by your school’s IT administrators under the university’s tenant. Because of this, I will guide you on how to contact them and suggest some information you can provide so the IT team can assist you more easily. 

Below is an email you can use to reach out to your university’s IT team. You can add any additional details if needed to receive the most appropriate support.

Dear IT Support Team, 

I am currently unable to access my university Microsoft Teams account because the system requires Microsoft Authenticator, but my device (Android 13) is being flagged as not meeting the minimum Android version. Since I need to access my Teams account on this device in order to receive class materials from my professor as soon as possible, I kindly ask for your assistance in resolving this issue. 

Could you please help with one of the following options: 

1/ Check whether my device meets the university’s policy requirements. 

Manage devices in Microsoft Entra ID using the Microsoft Entra admin center - Microsoft Entra ID | …

2/Enable an alternative MFA method (SMS, email, backup codes, or another authenticator app). 

3/ Reset my MFA registration so I can set up the authentication process again.  

Manage user authentication methods for Microsoft Entra multi-factor authentication 

• Sign in to Microsoft Entra - Microsoft Entra admin center 
• User -> all users. Select the user you want to act on, and then select "Authentication methods". then select "Require multi-factor authentication re-registration". 

Require re-enrollment MFA: This disables all previous authentication methods. You'll then be prompted to set up a new MFA authentication method the next time you try to sign in, so you can add a new authenticator app.  

4/ Provide temporary access to my account while the issue is being resolved. 

I would greatly appreciate your prompt support. Please let me know if you need any additional information from me. 

Thank you very much. 

Best regards,

_

*Note:

• Please note that in this case, you only need to find the global admin of your organization’s tenant. They are the ones who can help you check the issue regain access to your device.
• The global admin is usually someone in your school’s IT team or a system administrator. They manage Microsoft 365 settings, licenses, and security.
• Most schools have a helpdesk or IT support email. You can contact them to confirm who the global admin is.

If you still need my assistance, please come back with screenshots or any additional details so I can review it again and see if there’s anything more I can help you with. 

Wishing you the best with your studies!

Answer 3

Microsoft Authenticator itself does not require Android 15 in the provided information, but there are two important points:

1. For standard Microsoft Authenticator MFA (approvals, codes) on Android
   • Use the latest version of Microsoft Authenticator supported for Android 13.
   • Make sure:
     • The app is updated to the latest version available for the device.
     • Push notifications are enabled for Authenticator.
     • Battery optimization is turned off for Authenticator.
     • The device date and time are set correctly and the device is up to date.
   • Then sign in to Microsoft Teams with the university account and, when prompted, choose Send notification or Approve a request on my Microsoft Authenticator app and approve it in Authenticator.
2. For passkeys in Authenticator on Android
   • Passkey sign-in in Authenticator requires Android 14 or later. On Android 13, passkey-based sign-in cannot be used.
   • If the university has enforced passkey-only sign-in and the device is below Android 14, an alternative MFA/sign-in method is needed (for example SMS, phone call, or another authenticator method) or a device that meets the OS requirement.

If sign-in is blocked because only a method that the device cannot support (such as passkeys on Android 13) is allowed, contact the university IT/help desk and ask them to:

• Enable another MFA method for the account (SMS, phone call, or temporary reset of MFA), or
• Confirm the minimum Android version they require for Microsoft Authenticator and Teams access.
