Set up 2FA (Two-Factor Authentication)

Two-Factor Authentication (2FA) Setup Guide

All Office 365 accounts require a new security feature called Two-Factor Authentication (also known as 2FA, MFA, or Multifactor Authentication). After entering your username and password there will be an additional step. A unique code will be sent to you and you'll use the code to login. You may choose from several 2FA methods to receive your code.

2FA Methods

We support the following methods for 2FA:

Authentication Phone Receive a code by text message.
Receive a code by voice call.
Mobile App (Android/Apple) Receive a notification and Approve or Deny.
Use a code from the app.
Authenticator Token (Key fob) Use a code from the token.
