  • Best free MFA app for individuals: Google Authenticator
  • Best MFA software for small to medium-sized businesses: Cisco Duo

Multi-factor authentication requires users to present two or more pieces of evidence to prove their identity, such as a password and a one-time code sent to an authorized device. Requiring a secondary authentication factor reduces the risk of breaches caused by brute force attacks, social engineering and other methods used to steal or guess passwords, improving a company’s overall security posture.

For an example of how MFA prevents data breaches, read How to Prevent Phishing Attacks with Multi-Factor Authentication.

MFA software solutions provide multi-factor authentication for individual end-users, organizational workforces and customer-facing applications. Some platforms also offer identity and access management (IAM) features like single sign-on or additional functionality like threat detection. This guide compares the top multi-factor authentication tools based on use case, features and price.

6 Best Multi-Factor Authentication (MFA) Solutions for 2024 (4)

Google Authenticator is a free MFA app for Android, iOS, Wear OS and Blackberry. It generates time-based one-time passwords for a wide range of third-party software with very little setup. Google Authenticator is an extraordinarily useful MFA tool for individual end-users because it provides TOTPs for so many different applications and services in a single place. However, it doesn’t natively offer any multi-user administration functionality for organizations without being integrated with another management platform.
