Aside from the security concerns already noted I have two major questions:
1) How do I change my master password? It appears that all generated passwords would change as well. Even master passwords should be expirable and changeable.
2) I don't just use a password manager to manage passwords. I use it to manage _credentials_. I have a ton of credentials, so I need something that will remember the _usernames_ for me as well. Otherwise I don't just have to memorize the master password - I also have to memorize the usernames for the hundreds of different logins I'm managing. That's a non-starter.
