Modern security training take the same principle that sex Ed videos took when I was in school -- scare the viewers into never taking a chance. Our corporate training suggests to never connect to any public WiFi.

While it's obvious the business could monitor my web traffic, I'm curious if others could also use the publicly known WiFi password to decrypt my traffic.
