I've been using passwordsgenerator .net for ages, but had been offline for a few months. Today I found it's
back online here IMO it's the most complete tool out there and it's also safe since all passwords are generated client-side.
What do you use?
I don't use anything to generate my password.. I just press anything that comes to my mind and add the rules of the website I'm signing up with to it.
If I'm sitting on a couch.. My passord can be Couchblablabla

. I just always make sure that I back them up on the browser I'm using for reminder sake.
