I have started using lastpass's automagic password creation doodah to randomly generate my passwords, I am of course (foolishly) trusting them to stay in business for the rest of my life and paying the measly $10 / sorry, now $12pa to keep them "safe".
Is that safer than using the same memorable passwords (tiered for banking/work stuff/forum spamming/unimportant stuff) variations on the same theme just to memorise them? I dont know, SSO in a way but there comes a point in life where it all becomes too many to remember. What to do? For example, World of tanks did not allow me to use non alphabetic characters FFS, unbelievable how many times I use their "reset my password" facility as I cant remember it.
Might just get a big bunch of post-it notes and put them around the monitor like my Bosses do.
