Google Chrome and a few other web browsers have a unnecessary option that saves any password you type and actually shows it. Be careful because anybody who is using your laptop can actually check your passwords or add his password to the list without knowing.This is how it works:
1- Go to Google Chrome
2- Click on tools [top right side icon]
3- Options
4- Personal stuff
5- Manage saved passwords
6- Click on any website then press show
The best way to remove this option is to click on "Never save passwords" unless your computer is being used only by yourself.
This might be old news to a few people but I'm only giving the heads up.
