We require two-factor authentication (2FA) in order to provide an extra layer of security to your TrustToken account.
If you are setting up 2FA for the first time, we recommend using Google Authenticator or a similar third-party app like Authy. This overview from Google Authenticator describes how 2FA works and how to set it up.
If you need to reset 2FA, see our page "How do I reset my 2-Factor Authentication (2FA)?".
