Two-Factor Authentication (2FA), also known as two-step verification, is a security process where you confirm your identity or action through two different verification actions. With ChainEX, these actions are a login action in the form of a username and password combination as well as a confirmation of the login using your mobile phone.

Two-Factor Authentication (2FA) ensures a higher level of account security through its extra layer of authentication since unauthorized access to your account cannot be gained, even if someone can obtain your username and password.
