Google Chrome (on Windows): Password saving and management webapp LastPass offers a single space to drop your web site passwords and quickly use them on any browser—now including Chrome, through an extension available to development channel users.

LastPass works on Chrome similarly to how it does on Firefox and Internet Explorer, and it's a bit more convenient and functional than its bookmarklet form filler. The concept remains the same: you only have to remember your LastPass login, and LastPass remembers all your other passwords and, if you want, credit card and form data, too. Before you ask, here's how LastPass justifies its safety and encryption.
