Overview
The Microsoft Security Info dialog box allows you to update MFA.
The Microsoft Authenticator app passkey is the recommended default authentication method for users because of its phishing-resistant MFA security. Other PR-MFA methods include a Yubikey USB device and Windows Hello for Business (ECU-managed Windows computers).
Security info login
- Current users and recent alumni: mysignins.microsoft.com/security-info

Security Info options
Manage your account authentication methods through the Security Info dialog box.

1. Change your default
- From the Default sign-in method section, click/tap the Change link. A dialog box with a drop-down arrow opens.
- Click/tap your preferred default.
2. Add a method
Your ECU password is a backup method to your passkey. It is highly recommended you configure another method as a backup. If you already use Windows Hello for Business for your ECU-managed computer, this counts. You may wish to configure a USB Yubikey.
- Click the +Add a sign-in method link. The Add a sign-in method dialog box opens.
- Choose from the list.
- Follow the dialog boxes to configure your additional authentication method.
3. 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/
