What is Two-Factor Authentication?
Two-factor authentication adds an additional layer of security by introducing a second step to your login. It takes something you know (i.e.: your password), and adds a second factor, typically something you physically have (such as your phone). Since both are required to log in, in the event an attacker obtains your password two-factor authentication would stop them for accessing your account.
Why do you need it?
Passwords are increasingly easy to compromise. They can often be guessed or leaked, they usually don’t change very often, and despite advice otherwise, many of us have favorite passwords that we use for more than one thing. So Two-factor authentication gives you additional security because your password alone no longer allows access to your account. How does it work?
