But do you think it would be very difficult to use in your company? Learn what two-factor authentication is and see how easy it is to use and integrate with an existing system.

Several large, security-conscious companies have used two-factor authentication. With the tightening of digital laws in the way user data is stored, companies are looking for increasingly effective solutions to validate any type of action by their users. On a broader scale, this works like a police background check in Australia.

What is two-factor authentication?

It is an additional security feature that is used by several online service providers. It works as an extra layer of security for a login process, for example, where the user is required to provide another way to validate its authenticity.

In theory, two-step authentication is that you must have something more, and not just the password, to log in for example.

Is it safe to use two-step authentication?

So far, two-step authentication is the best alternative in terms of protection and security. In addition to protecting the service provider, it offers a benefit to the end user, who is notified when someone has guessed their password, for example.

As noted above, if you have received two-factor authentication on your device and do not recognize the attempted login, you must take the following precautions:

  • change your passwords
  • revalidate your devices where you have saved passwords;
  • scan your devices for viruses or malware.

By taking these precautions, you guarantee the security of your account and keep your data safe with the help of two-step authentication.

In general, a unique TOKEN or PIN is sent to the user to prove their authenticity. There are several ways to implement and use two-factor authentication to ensure the security of your users, we list them below and their advantages.

Two-factor authentication by SMS

SMS is the most used way to validate the authenticity in two factors because the vast majority of users carry their cell phones at all times. Thus, the services can guarantee that users will receive the verification PIN or TOKEN.
