Office 365 Two-Step Verification

By setting up 2-step verification, you add an extra layer of security to your Office 365 (aka LawKey) account. With Two-Step, after logging in with your O365 email and password — you’ll be prompted to verify your identity—the second step—using a device in your possession, such as a mobile phone.

The Microsoft Authenticator app is the easiest verification method to use. Once the app is installed on your mobile phone, it’s just one click instead of typing in a 6-digit code. And if you travel, you won’t incur roaming fees when you use it. Instructions for setting up and using the Microsoft Authenticator app.

General instructions on using two-step in Office 365: Setting up two-step verification.

We strongly recommend setting up more than one verification method.

“What happens if I get a new phone?”

If you are using the recommended Microsoft Authenticator app, you will need to re-configure the app any time you get a new phone or mobile device.

You can do this by going to your Office 365 My Sign-ins: Security Info page 

Note: you may need to use the option “Sign in Another Way” on the MFA screen in order to access your Office 365 profile page.  You can select the option to receive a text code since you do not have your Authenticator app set up yet.
