Two-factor authentication, popularly known as 2FA, is a multi-factor authentication method requiring users to add a second factor to authenticate their identity.

If a password gets breached, there’s an additional level of security to prevent total account loss.

Statistics reveal that two-factor authentication is higher among employed than unemployed individuals. It also shows that 32.4% have set 2FA across all their applications, with the prevalence rate growing to 79% in 2021.

Below are two-factor authentication statistics for a broader view of this authentication method.
