How do I set up 2FA?

2-Step Verification (commonly known as two-factor authentication, or 2FA) acts as an extra layer of security for your account, and it is required in order to make deposits & withdrawals from your account, it comes in the form of a one-time passcode (OTP) generated by the Google Authenticator app (SMS, and Yubikey coming soon!). 

You will be prompt to set it up during sign up, however if you didn't do it then, you can follow this visual guide to help you set it up.

We recommend Google Authenticator for users, It doesn’t require an internet connection or phone service to use, and is more secure than SMS due to being offline and local to your device.

Follow this visual guide step by step to set up 2FA in your account:
