Two-factor authentication (2FA) is an additional security layer for your account that helps to address the vulnerabilities of a standard password-only approach.
To activate 2FA you need to download and install a mobile application such as Google Authenticator on your mobile phone. Once set, the application will generate 6 digit codes that you need to use in combination with your email and password in order to gain access to your account.
2FA is also required if you wish to enable “Trading” for your exchanges.
