Two-factor authentication(2FA) is a method of protecting your account and related data using two different types of validity checks.
When you sign in to an account, you usually enter your login and password. In this case, we can say that your password is one of your authentication factors. If you enable 2FA, you’ll need to provide one more unique code to access your account. This code is usually provided by SMS or with a special application.
2FA gives an extra layer of security to your personal information and funds. You can enable 2FA on your CEX.IO account using the SMS method or the Google Authenticator app.
