Not really a Zaurus thing, but too useful not to share...
http://hubpages.com/hub/SuperGenPass-Simpl...sword_Generatorbasically, you use a master password which uses the domain of the website you're on to generate, via a one-way md5 hash, a password for each website you visit.
thus you can have a unique pass for each site yet only need to remember the master pass
since it uses a pretty secure algorithm, as long as your master pass is unguessable and kept secret, you should be fairly safe!
p.s probably a good idea to save the master password generator page along with the javascript, so if the webpage disappears you can regenerate the bookmarklet.. so save this page "complete"
