Why we use passSymbols here? Should we use symbols instead?

Why dont we use assert and require for ensuring that we have the expected results?

Why usernames is not username? We are passing a single user.

We can determine if we are proxyadmin by running simply something like this, correct?
len(username) > 0 && username[0] == users.ProxyAdmin

Also this can be pre calculated insteda of resolving it for every len(passwordLen) iteration

I also think these can be precalculated in general
e.g.
firstCharSymbols = excludeChars(passSymbols, "*:;")
otherSymbols = excludeChars(passSymbols, ":;")
