Two Factor Authentication (2FA) is used to heighten security by adding an additional layer of security to verify identity and prevent fraud. One of the most popular ways to perform 2FA is to have a single use, time sensitive PIN code sent to a user’s mobile phone. Having passed the first level of security, when prompted, the user puts the PIN code from their mobile phone into the system they are trying to access, thus proving that they are in possession of the SIM card associated with that number.
