Set up 2-step verification for Office 365

Once your admin enables your organization with 2-step verification (also called multi-factor authentication), you have to set up your account to use it.

By setting up 2-step verification, you add an extra layer of security to your Office 365 account.
When you sign in with your password, a code sent to your phone as a second verification that it is you and not someone else with your stolen password.

• You will need to check if your admin has turn on multifactor authentication.
  If they haven’t, when you try to do these steps you won’t see the options in Office 365.
• Sign in to Office 365 with your work or school account with your password like you normally do.

We strongly recommend setting up more than one verification method. For example, if you travel a lot, consider setting up Microsoft Authenticator for your verification method. It’s the easiest verification method to use, and a way to avoid text or call charges.
