An In-Depth Look at Multi-Factor Authentication
Multi-factor authentication (MFA) is a vital security measure designed to protect user accounts and confidential information. By implementing MFA, users are required to present at least two separate authentication factors to confirm their identity and access a system.
How MFA Functions
MFA works by combining different factors from these three categories:
Something the user knows (e.g., a password or secret question)
Something the user possesses (e.g., a security token or mobile device)
Something the user is (e.g., biometrics like a fingerprint or facial recognition)
By demanding multiple factors, MFA decreases the chances of unauthorized access to accounts and data, even if one factor, such as a password, is compromised.
Why Use Multi-Factor Authentication?
While using only a username and password may be convenient, it's not always secure. Cybercriminals often take advantage of weak or stolen passwords to gain unauthorized access to accounts. MFA adds an additional layer of security, making it more challenging for attackers to infiltrate accounts and access sensitive information.
Multi-Factor Authentication in Microsoft 365
Microsoft 365 employs MFA to improve security for its users. The service provides a variety of authentication methods, including:
Phone call
Text message
Microsoft Authenticator app
Third-party authenticator apps
Hardware tokens
Users can select the method that suits them best and follow the instructions to set up MFA on their accounts.
Activating MFA for Your Organization
Administrators can activate MFA for their organization's Microsoft 365 accounts by following these steps:
Sign in to the Microsoft 365 admin center
Go to the "Users" section and select "Active users"
Choose "Multi-factor authentication" from the "More" menu
Enable MFA for individual users or in bulk
By enabling MFA, organizations can significantly enhance their security posture and protect their valuable data and resources.
