JIRA password security

May it be possible to encrypt the Jira password or to ask for it from the console?

AFAIK a there is no option in Jira to create a "special" User out of the licence for REST Calls so we have to use a real persons Account with his/her original password.

And is the pom.xml with password saved into the jar in META-INF ? So anyone with winrar i.e. can read your Jira password in plaintext ? 

thanks in advance!
