Once your admin enables your organization with 2-step verification (also called MFA), 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. You sign in with your password (step 1) and a code is sent to your phone (step 2).
-
Check your Office 365 admin has turned on multi-factor authentication for your account (This has been done for everyone). If they haven't, when you try to do these steps you won't see the options in Office 365.
-
Click here to begin setting up your MFA by signing in to Office 365 with your work or school account with your password like you normally do. After you choose Sign in, you'll see this page:
-
Choose Set it up now.
-
Select your authentication method and then follow the prompts on the page. (For most users, it's recommended to choose to use their phone number for simplicity rather than the authenticator app unless you are an admin or someone with access to high-security or confidential type of information, and then the Authenticator App is a better option to provide higher-level security protection. You can also add the authenticator for simplicity, but this way, if you ever change your phone, you always have the text option as a backup and you can reset the app functionality for your new phone)
-
After you verify your alternate contact method, choose Next.
-
You'll get an app password that you can use with Outlook, Apple Mail, etc. Choose the copy icon to copy the password to your clipboard. You won't need to memorize this password.
-
Once you complete the instructions to specify how you want to receive your verification code, the next time you sign in to Office 365, you'll be prompted to enter the code that is sent to you by text message, phone call, etc.
To have a new code sent to you, press F5.
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.
