Passwords: This Necessary Evil [infographics]

computer-large-newPasswords are ubiquitous. We all use them and despite the fact that we keep grumbling that they aren’t good enough, we still rely on them in order to protect our most precious information like bank account details, personal and electronic commerce details and such like. What I learned today while looking at Ken Peterson’s infographics is that passwords, as it were, aren’t a new invention. They were created with WWII for cyphers and were adapted in 1972 to become the classic passwords as we know them. Yet, however important, passwords are still misused by users who use the same passwords for multiple sites (73%), use the same passwords for all their sites (33%), or even use the word “passwords” and other niceties as a secret code. all sources for stats are quoted at the end of the picture.
