It may have escaped some people's notice that three big internet companies were hacked last week: Linkedin, Last.fm and eHarmony. Today I would like to explain why using one password for everything is a BIG bad idea and the best way to have a unique password for all sites that is easy to remember.

I'd like to start by saying that this is not an attack on individual, business establishment or company.

Two days ago I got a call from a customer regarding an offer he had received from another Computer Repair Company. The offer was for a "Free PC Health Check".
