What is Two-Factor Authentication and How Does it Work?

What is Two-Factor Authentication and How Does it Work?

There are a number of ways that you can protect yourself online, and one of the things you can do is to start using two-factor authentication.

You probably have seen two-factor authentication even if you aren’t sure what it is. For instance, if you do online banking, your bank might text a code to your phone or email when you try to change the password. This is two-factor authentication. It’s basically just an extra step that confirms that you are the account owner. This makes it more difficult for hackers to get into your account, too. Not only do they need a password, they also need access to your smart phone or email account.
