LastPass
@hector Looking briefly on their site it looks like there is actually a database with your passwords, somewhere. The beauty of LessPass is that it is stateless, so my passwords aren't stored anywhere :) They are generated each time using a combination of multiple things (the site I'm trying to log in, my "master password", etc.)
@hector Yeah, it has some advantages for sure, but also some trade-offs. I've been using LastPass for a while which is using this paradigm of storing the passwords somewhere, so I'll try LessPass to see how it goes. In the end, if I ever forget any of the seed data I can always reset the password. I don't keep really important passwords (the ones that cannot be reset by email) on these services.
