Protect an Outlook.com Account with 2-Step Verification

To secure your Outlook.com account, start with a strong password. Then, add two-step verification as a second way to log in. When you log in with two-step verification, you'll receive a generated code in a text message to your phone, in an email message, or in an authenticator app. After you set up two-step verification, exempt browsers on devices and computers only you use from the need to enter a code. For the flexibility afforded by POP access and IMAP in email programs, generate app-specific passwords.

Instructions in this article apply to Outlook.com and Outlook Online.
