Hackers take advantage of password recycling by testing stolen usernames and passwords against popular websites. This occurs when people use the same password for multiple accounts. Password recycling is also a common problem. As a result, some people write down their passwords, increasing the risk that an unauthorized individual will be able to access a private account. Many people now have dozens of online accounts, making it difficult to remember the password to each one. The use of two-factor authentication helps users avoid the consequences of several password-related problems. Therefore, the authentication will fail, preventing an unauthorized user from gaining access to your account. For example, if a website is set up to send a code to your smartphone as the second form of authentication, there’s a good chance the hacker won’t have your smartphone in his or her possession. Two-factor authentication is more secure because even if your password has been compromised, there’s a good chance the hacker won’t have the second piece of information needed to complete the authentication process. Something you are such as a scan of your fingerprint or the iris of your eye.Something you have like your smartphone or credit card.Something you know such as your mother’s maiden name or a personal identification number.Depending on how 2FA is set up, you may have to verify your identity using one of the following methods:

When two-factor authentication is enabled, you must go through a second authentication process once you enter your username and password.
