There may be other password vaults out there, but i don't know of them....the only one i have used is APV and i have not needed to look anywhere else. If it ain't broke, don't fix it. It is also good for multiple users. Each user remembers a single phrase, word, song title, or event (in words) and then the vault opens, launches at your command, and will sign you in with a quick cut and paste. Nicely done Acerose. I've passed this gem onto my friends and a few of them are using it. I like the simplicity of the program and the strength and flexability of the password generating options.
