2-factor authentication (2FA) is a required security feature on GateHub, providing a second layer of protection when logging into your account or performing actions within (like initiate transfers of funds, trade or exchange orders, etc.).
It is a two-component authentication method that requires a smartphone (or tablet) with an installed app (like Google Authenticator or Authy) that generates a one-time-valid 6-digit code every 30 seconds.
