How to set up 2FA on the platform
Follow the below steps to set up two-factor authentication via your PC:
Log into your account (or register for an account).
Access the ‘Settings’ dropdown menu in the navigation bar at the top of the window.
Select 'Two-factor authentication'.
On-screen instructions will guide you through the setup process for mobile app activation – via scanning a barcode or manual entry – or text message (SMS) activation.
Once you’ve selected either mobile app or text message for your 2FA method for withdrawals, you’ll instantly be protected for withdrawals. You can also choose to enable 2FA when logging in to your account for additional security, by selecting the ‘Enable 2FA for login?’ box.
To amend or switch off the 2FA security measure settings, simply update the details in the same section.
