Two-factor authentication


  1. Two-factor authentication Two-factor authentication (2FA) is a technology that provides a stronger security/identification of users by means of the combination of two different components : something that the user knows (username and password) and something that the user possesses (a Time-based One-Time Password application for smartphone. See below).
  2. The Time-based One-Time Password (TOTP) To use the two-factor authentication method, you will need a Time-based One-Time Password (TOTP) application on your smartphone. This app generates a code that changes after a certain period of time.
