2-Factor Authentication is an extra step added to logging into an account that helps prevent unauthorized access. When you log into your account you’ll be prompted to provide a token provided by an Authenticator application that’s cryptographically generated from a private code only shared between WinterNode and the Authenticator application.
As long as you don’t share those tokens or that code and a third party doesn’t have physical access to the device that you’re using for your Authenticator application. This is a nearly foolproof method of authenticating. For redundancy sakes, you can even save the original token in a password manager or other safe location, in case you lose your device or have multiple devices set up with an Authenticator application ready to go.
