I could describe it in the code, but not making the option visible to the end
user. This way, the option won't show up in the `cqlsh --help` output or the
[HTML
document|https://cassandra.apache.org/doc/latest/cassandra/tools/cqlsh.html],
but if anyone reads (or searches it in) the source code of cqlsh.py, the option
will be clearly documented.

> Separating CQLSH credentials from the cqlshrc file
> --------------------------------------------------
>
> Key: CASSANDRA-16983
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16983
> Project: Cassandra
> Issue Type: Improvement
> Components: Tool/cqlsh
> Reporter: Bowen Song
> Assignee: Bowen Song
> Priority: Normal
> Labels: lhf
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Currently, the CQLSH tool accepts credentials (username & password) from the
> following 3 places:
> 1. the command line parameter "-p"
> 2. the cqlshrc file
> 3. prompt the user
> This is not ideal.
> Credentials in the command line is a security risk, because it could be see
> by other users on a shared system.
> The cqlshrc file is better, but still not good enough. Because the cqlshrc
> file is a config file, it's often acceptable to have it as a world readable
> file, and share it with other users. It also prevents user from having
> multiple sets of credentials, either for the same Cassandra cluster or
> different clusters.
> To improve the security of CQLSH and make it secure by design, I purpose the
> following changes:
> * Warn the user if a password is giving in the command line, and recommend
> them to use a credential file instead
> * Warn the user if credentials are present in the cqlshrc file and the
> cqlshrc file is not secure (e.g.: world readable or owned by a different user)
> * Deprecate credentials in the cqlshrc, and recommend the user to move them
> to a separate credential file. The aim is to not break anything at the
> moment, but eventually stop accepting credentials from the cqlshrc file.
> * Reject the credentials file if it's not secure, and tell the user how to
> secure it. Optionally, prompt the user for password if it's an interactive
> session. (Think how does OpenSSH handle insecure credential files)
