Microsoft Authenticator Problem

Kayleigh Innes 0

Hi there, my account on my Authenticator app says that there is an error and I need to sign into my account. Then when I try and sign into my account it says I need an Authenticator code but I’m literally logging in on the Authenticator app with the app not downloaded on any other devices.

Hello Kayleigh Innes

In this situation, it seems that you are stuck in an Authenticator loop.

To support you, might I reconfirm your account type first?

Work account (@companyname)
Educational account (@edu)
Personal account (@outlook.com, @hotmail.com)

If your account belongs to an organization (company or school), you no longer have access to your old phone, and you cannot use any other verification method (such as a phone call, SMS, or email) to sign in, you will need to contact your IT Administrator or Global Administrator. They are the only ones who can reset or update your authentication methods so you can regain access to your account.

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.

*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 regain access to your account.
The global admin is usually someone in your school’s IT team or a system administrator. They manage Microsoft 365 settings, licenses, and security.

I hope I’ve been able to help in some way. I look forward to your update

Take care, and have a nice day!

This is usually a sign-in loop: the account is configured to require Microsoft Authenticator, but the currently registered Authenticator instance is no longer available or usable on the device.

Try these checks first:

Make sure the Authenticator app is unlocked.
- If the app is locked, the entry box may not appear and authentication can fail.
Make sure notifications are enabled for Microsoft Authenticator.
- Silent or disabled notifications can prevent the prompt from completing.
- Also check for any text-message authentication codes that may have arrived silently.
Update Microsoft Authenticator.
- Older app versions can cause sign-in problems.
- Microsoft does not support app versions more than 12 months old.
Check connectivity.
- Switch between Wi‑Fi and mobile data.
- Make sure Airplane mode is off.
- If using VPN, disconnect it and test again.
Check device settings.
- Make sure the device date and time are correct.
- Make sure the device OS is up to date.
If the app shows a temporary error such as "Something went wrong. [4s8qz]":
- Wait a moment and try again.
- Open Authenticator and confirm it launches normally and the account is listed.
- Restart the device.

If the account is a work or school account and no other verification method is available, the next step is to contact the organization’s IT admin or helpdesk. They can investigate the Microsoft Entra sign-in logs, and if needed, help reset the MFA setup so Authenticator can be registered again.

If the account is a personal account, send logs from Authenticator by opening the app menu and selecting Send feedback, then contact Support.
