lost my phone due to which i lost access to authenticator app. now, i cant access to my work portal

If you have lost your phone and can no longer access the authenticator app, you will need to have another cloud services admin reset your Multi-Factor Authentication (MFA) settings. Here are the steps they should follow:

1. Sign in to the cloud service portal as an admin.
2. Go to the MFA management page.
3. Select the checkbox for your account.
4. Choose Manage user settings.
5. Check the box for Require selected users to provide contact methods again and then select Save.

After this, you should be able to set up your MFA again with a new device.

If you need further assistance, consider reaching out to your IT support team.

Hi. I'm Brian and I'll try to help.

If you are using a business account with Microsoft 365 for Business, you will need to have the tenant administrator help you. Microsoft cannot help. The whole purpose of using an authenticator is to make it impossible to access the account without the password and the code from the authenticator.
