Passwords really annoy me. I use a variety of standard passwords, and that combined with different sites having different requirements for password qualities, I go insane. Or at least, I used to go insane, until recently when I started using LastPass, which stores and manages all my passwords. You can also give someone else access to an account temporarily by giving them access to it via LastPass. It’s nice and I’m less annoyed now, which is priceless.
