  • Mobile Code
  • QR Code

Explanation

Two-factor authentication (also known as 2FA or 2-Step Verification) is a technology patented in 1984 that enables confirmation of a user's claimed identity by using a combination of two different components. These components are usually a password and username as well as something that only that user would have immediately at hand, like their mobile phone.

Using a username and password together with a piece of information that only the user knows makes it harder for potential intruders to gain access and steal that person's personal data or identity.
