Overview
When logging in to ECU resources, you are required to authenticate (verify) your account through one of three methods: Phone (call or text), Microsoft Authenticator app or Windows Hello for Business (ECU-managed Windows 11 computers only).
This tutorial explains how to:
- Access Microsoft 365 account settings to manage methods.
- Change your default authentication method.
- Add, change or delete an authentication method.
- Sign out of all devices if your device is replaced, lost, stolen or hacked.
- If you need further assistance, submit the ECU PirateID Password and Multifactor Reset Request.

Authentication methods
The Microsoft Authenticator app is the recommended default method for all users as it works internationally and can generate a code with no internet or cell service. It is also recommended that you configure multiple authentication methods.
The example here shows the user configured Microsoft Authenticator notification as the default sign-in method and also added a phone number,

1. Change your default authentication method. You can change your default sign-in method by clicking the link and choosing a different sign-in method from the list. The Microsoft Authenticator app is still the recommended default app.

2. Add an authentication method. It is highly recommended that you configure multiple authentication methods: Microsoft Authenticator App notification, number match or passkey (mobile device required), Yubico security key (available for purchase at Dowdy Student Stores and through PORT), Phone call (landline or mobile), Phone text (mobile). You can add up to three different phone numbers for authentication.
NOTE: The Password and Email options are password change and verification methods and different from MFA.

3. Change your authentication phone number. Click the Change link beside the phone section. Add the new number and decide whether to verify through text or phone call. Click Next then verify through the new phone. A message verifies the new number in the system.

4. Lost device. If you lose your mobile authentication device, Microsoft recommends you sign out of all devices.
Click the Sign out everywhere link in the Security Info area. A dialog box opens explaining that, if you have lost your device, you need to sign out of all sessions/devices. Click OK to continue.
You can also check the Recent Activity page to see where your account is active to make sure you are the only user signed in on your account. mysignins.microsoft.com/
