Two-factor authentication (2FA) is an optional layer of security to your Trading 212 account, designed to ensure that you’re the only person who can access it.
When enabled, you’ll be asked to enter a special six-digit authentication code generated by a two-factor authentication app, like Google Authenticator or Authy.
This additional step helps make sure that you, and only you, can access your account.
