Why you should treat passwords like your toothbrush

A Guest Article by Stefan Lüders.*

Your password is your entry token into the digital world. eBay, Amazon, Facebook, Twitter – your company accounts – all ask you for a password to authenticate and prove that you are you. And vice versa: If I know your password, I can impersonate you and use your money to buy from eBay or Amazon, post nasty messages on your Twitter or Facebook profile, or misuse computing facilities of your company or organization in your name!

Would you give me your UBS bankcard and its PIN number? Of course not!
