Overview

If your staff share a Microsoft 365 account, setting up Multi-Factor Authentication (MFA) on a single mobile device may not be a valid solution. In cases where staff are all based in the same physical location verifying the account sign in via an automated phone call is an ideal solution.

Instructions

  1. Log in to your Microsoft 365 account at the following URL: https://mysignins.microsoft.com/security-info
    (If prompted whether to sign in using a “Personal” or a “Work/School” account, select the “Work/School” option to sign in with your Conetix supplied account).
     
  2. Click the Add method button:

  6. Click Next:

  7. Microsoft’s sign in verification service will now call the entered landline number, follow the prompts to verify the sign in.
  8. After successfully verifying the sign in, you will see a message showing your phone was added successfully:

  9. Click Done to finish.

Now when multi-factor authentication is required for a new sign in, the Microsoft service will call the designated landline number to verify the sign in.

Warning

We highly recommend training staff not to accept verification calls if they are not expected.
