Passwords are also susceptible to вЂњman-in-the-middleвЂќ attacks, where a hacker can intercept your password in plain text when you connect to the server and then use it whenever they want.ДЄ private key connection,В however, doesnвЂ™t allow man-in-the-middle attacks. A private key on your local computer isnвЂ™t as vulnerable as a password. Something you have, on the other hand, is a lot more difficult to fake.
