I was wondering about the password change scenario and the FAQ at your link gives some clue. So basically, if you are using this scheme/tool for your passwords than you are basically remembering the changing words (bills1, bills2 etc). This isn't really any different than remembering your passwords (if you are into making password strings of your own). I guess a local password manager is good enough repository for passwords as it also lets you generate passwords.
