What is two-factor authentication?
Two-factor authentication adds a second level of authentication to the login of an account.

How is 2FA vulnerable to hackers?
To hack two-factor authentication, criminals must acquire the physical component of the login or must gain access to the cookies or tokens placed on the device through the authentication mechanism. This can happen in a number of ways, including a phishing attack, malware, or credit card reader skimming. However, there is another way: account recovery.
