On the main page, please click on the menu icon in the top left corner of the screen and open “Security Settings”. Open “2FA Authentication” and turn on “Enable 2FA” option. In the next window, you will be provided with QR code which should be input into Google Authenticator or Authy and a secret key which should be stored in a safe place. The secret key is used to recover the access to your GoodX account in case your mobile phone is lost. Once you link Authenticator to your account, you should enable 2FA verification for your login. Optionally, you can enable 2FA verification for the rest of operations in the list.
