'@' or '?' in passwords

[ivosanchez]

hi. thanks for responding to the other issue -- and for writing the software -- it's kind of great. gonna try deployment in aws again in a bit, for now, I was able to make it work locally. I could not figure out that although it does not complain during setup if you enter a password including a non-alphanumeric character such as '@' or '?' , it wont be able to fetch later during authentication in the backend. It works fine if password does not contain any of such characters.
