EPP password change

Hey,

I am using node-epp-restful.js and I need to do a password change for a test parcours.
As far as I can see this needs to be done at login. As node-epp-restful.js directly logs in when it is started I am not sure how a password change can be performed and if this is even implemented.
Feedback on this would really be appreciated before I start implementing something myself.
