Last updated on October 16, 2024

Multi-Factor Authentication (MFA) for Office 365 is a secure way of user authentication that prevents cybercriminals from gaining access to an account even if they know the password to that account. MFA for Office 365 requires users to present at least two proofs of identity. In the first step, users provide their login and password like they always do. In the second step, users must complete a strong authentication factor, such as approving a Mobile Push authentication request.

Overview of MFA for Office 365

The purpose of this document is to add Rublon MFA to the Office 365 authentication process and enable Multi-Factor Authentication (MFA) for Office 365 (Microsoft 365) users. To achieve that, you must install the Rublon MFA for Microsoft AD FS connector. All required steps will be described within this document.

Benefits of Enabling MFA for Office 365

  • Strong Protection Against Cyberattacks – Multi-Factor Authentication prevents Ransomware, Account Takeover (ATO), and other types of malicious attacks.
  • Low Subscription Cost – Only $2 per user per month.
  • Multiple Authentication Methods – Users can authenticate using one of many authentication methods.
  • Fast Single Sign-On (SSO) – Users can sign in to Office 365 and other applications without reentering their passwords.
  • Robust Access Policies – Administrators can adapt MFA to the organization’s unique requirements.
