Just DONT entrust it your passwords at the moment.
Just a script to save all your passwords in a crypted db.
First you add manually users and their passwords:
$ rubypw add [username]
or import them
$ rubypw file [filename]
from a file like this:

username2 password2
Then you get the password you need with:
$ rubypw get [username]
Moreover you can:
list all your users and passwords:
rubypw list
delete an user:
rubypw del [username]
just generate a random password:
rubypw generate [password lenght]
and dump your db to a qrcode png file:
rubypw dump [filename]
