Two-factor authentication (2FA) is an extra security method that requires two different forms of verification to log in to an online account. We all know that online accounts, such as your email or electricity bill, require a username and password. 2FA is when your online vendor requires you to enter an additional security code after you provide your username and password. This unique code is sent to another of your accounts, such as an email or cellphone. When you receive it, you enter the security code on the vendor's website to complete the login process. This process is an example of using 2FA to log in to your accounts.
