To greatly reduce the likelihood of fraudulent activity taking place should your login ever become compromised, customers can authenticate with the Authy App. Authy, allows a smoother, safer and quicker way to authenticate. With Authy, you will also have the option to authenticate on multiple devices, including mobile, tablet and desktop. Find out more here.

How does it work?

Once you have enrolled with Authy, you won’t have to input the 6-digit code each time you book a trade or make a payment. Instead, you will receive a push notification. Simply click on this notification to be directed to a page prompting you to either ‘approve’ or ‘deny’ the trade or payment.

If you choose to verify with SMS, then you will receive a 6-digit code that you will need to input when you book a trade, make a payment, or add a beneficiary. Authy provides you with the choice to authenticate via:

  • Authy App
  • Authy Chrome Extension/Web App
  • Authy Desktop App
  • SMS
  • Phone verification currently only applies to SMS authentication and does not yet apply when downloading the Authy App
