Two-factor authentication (also called "2FA") is quick and easy to set up, and is most definitely worth your time.
It is a process that requires users to verify their identity using by using code which is beyond just requiring you to log in with your username and password. You will also be asked to enter a code that is sent to your mobile phone through an authenticator app such as Google Authenticator or Authy. This code is unique, randomly generated, and constantly refreshing and therefore very difficult to hack.
Having 2FA enabled on your account means that if someone tries to gain access to your account by stealing your password, 2FA will provide a second layer of protection. The system will require that person to provide a code that is accessible only from your mobile phone. Since the chances of that person also having access to your mobile phone is significantly slim, your coins.co.th account will be much better protected.
