Introducing a two-factor authentication (2FA) module on the login page is another good security measure. In this case, the user provides login details for two different components. The website owner decides what those two are. It can be a regular password followed by a secret question, a secret code, a set of characters, or more popular, the Google Authenticator app, which sends a secret code to your phone. This way, only the person with your phone (you) can log in to your site.
I prefer using a secret code while deploying 2FA on any of my websites. The Google Authenticator plugin helps me with that in just a few clicks.
