"I don't know what else you could want."
One password to memorize. Terrific! Fills out forms for you and generates passwords to your preference. I can't believe it is free. The offer a paid one but why would you want to.
Signing in some sites don't work. Don't know why but it is easy to copy usernames and passwords and post them yourself.
Not perfect but darn near. You can't beat it for the price.
