One of the best ways you can protect your user accounts is to use a second form of or sign in known as multi-factor authentication, or MFA. MFA means that users will enter a code sent to their phone or use an authentication app to sign in to Microsoft 365. 

To turn on multi-factor authentication:

  1. In the Microsoft 365 admin center, choose Setup.

  2. Under Turn on multi-factor authentication, select View.

  3. On the Turn on multi-factor authentication (MFA) page, review the information, including any alerts and their impact, and then choose Get started.

  4. On the Strengthen sign-in security pane, verify that the Require multi-factor authentication for admins and Require users to register for multi-factor authentication and block access if risk is detected check boxes are selected, and then select Create policy.

Multi-factor authentication is now activated. The next time you sign in to Microsoft 365 Business, you and your users will be asked to set up a second form of sign in.
