Your Microsoft 365 for business plan includes security capabilities:

  • Antiphishing, antispam, and antimalware protection for email

  • Multi-factor authentication (MFA), which can prevent hackers from taking over if they know your password

  • Administrator accounts (also called admins) have elevated privileges, making these accounts more susceptible to cyberattacks

  • Preset security policies

  • Protected environment for communicating and sharing files with Microsoft Teams, OneDrive and SharePoint

During initial setup or when you log out and log back in to your Microsoft 365 account, a security dialog box appears reminding you to set up basic security:

Set up Multifactor authentication:

  1. In the Help us protect your account dialog box, select Next.

  2. If you don't have the Microsoft Authenticator app for iOS, select Download now.

  3. After you've downloaded Authenticator, select Next.

  4. Select the phone method to receive codes by text.

  5. When you receive a code by text, type code number into the box, and select Next.

  6. Select Next, and open Authenticator on your phone.

  7. Scan the QR code on your screen with the Authenticator app, and select Approve when you receive the phone notification.

  8. Select Done.
