Setting up MFA on your Office 365 account is a simple process and can be completed in about 5 minutes. The video on this page explains how to set up MFA and also explains how to use App Passwords. For step-by-step procedures, please follow this guide:
Choose Set it up now.
Select your authentication method and then follow the prompts on the page. Or, watch the video to learn more.
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.
