Each Investor can choose whether to use two-factor authentication as an extra layer of security tool or not. Two-factor authentication helps to protect your account from unauthorized access as a result of a compromised password, phishing attacks and other cybercrime. In order to ensure that the only person logging into your account is you, the sign-in with the two-factor authentication will require your password and your Security Key which you will type in via an app on your phone. This means that even if someone has your password unless they also have your phone or your other trusted device with them, they will not be able to access your account.
