Accepting the raw password on the command line will mean that it is
persisted in the terminal history and available to any other processes running.
It is more secure to use

> Simple Username/Password Authentication

> Key: NIFI-1614
> URL: https://issues.apache.org/jira/browse/NIFI-1614
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: James Wing
> Priority: Minor
>
> NiFi should include a simple option for username/password authentication
> backed by a local file store. NiFi's existing certificate and LDAP
> authentication schemes are very secure. However, the configuration and setup
> is complex, making them more suitable for long-lived corporate and government
> installations, but less accessible for casual or short-term use. Simple
> username/password authentication would help more users secure more NiFi
> installations beyond anonymous admin access.
