Multi-Factor Authentication
An introduction to multi-factor authentication. Resources offering multi-factor examples and approaches. Learn how to authenticate users with an MFA solution.
Multi-factor authentication (MFA) is the practice of chaining a number of authentication methods together. Using multiple authenticators significantly reduces the risk of user accounts being compromised due to password theft. An example of a common scenario is to combine username/password with a second factor such as an SMS to a phone, a key fob or a biometric. Today MFA is considered best practice and help protect both users and organizations from cybercriminals.

Introduction to Multi-Factor Authentication
Multi-factor authentication is an authentication method that relies on more than one factor when determining whether to grant access to a user.
