In a former life I learned quite a bit about keyloggers. Anyone who does that gets a hefty dose of paranoia - you visualise a shadowy figure leaning over your shoulder watching your every move...
Even after my escape into the real world, some of the paranoia remains.
High-strength passwords - at least a dozen random characters/symbols
Different passwords for every login
A single encrypted file on an encrypted memory stick contains all the passwords
Use password manager wherever possible (thanks for the link, C1ay - it looks interesting)
Where password manager can't be used (new computer for instance), copy/paste from file
using the mouse right-click or edit pulldown, not ctrl-C/ctrl-V. Some keyloggers can convert the ctrl-V keypress into the paste string. Back then, mouse clicks weren't readable via keylogger - if they are now, I'm not sure I want to hear about it!
Change passwords frequently - especially if I've used them on a machine I don't entirely trust
My memory isn't what it was. If I have to remember a password (e.g. the encrypted password file) I think of a few words connected to what I'm doing at the time (say, George Hotel, desk), change them around using my own leet-similar code (G30rg3 H0t37 d35k) and connect with an odd character (G30rg3!H0t37!d35k).
And a few other things I'm too paranoid to talk about!
