7 Best Two-Factor Authentication Solutions

What makes a two-factor authentication solution convenient for an enterprise and which products should companies consider to implement? In this article, we will cover 7 most suitable data protection tools offered by well-known two-factor authentication service providers.

A standard procedure of getting access to a network account consists of entering login details: a login and password. This is a single factor authentication. Two-factor authentication (2FA) is an additional data protection measure that implies an extra step to a common log-in procedure. Unlike a single factor authentication requires users to enter password and login (something they know) to get access to data, 2FA may require entering one-time password received on a personal mobile device (something users have) or inherence confirmation, e.g. biometrics (something users are).

Two-factor authentication solutions allow companies to better protect their data and avoid unauthorized access to it. Though, a set of features and characteristics of every tool can be totally different from vendor to vendor.
