how can I authenticate jasper reports server as part of link or bypass authentication

I am using Jasper web services to access a report through a link. For example:

http://localhost:8080/jasperserver/rest_v2/reports/reports/Statement.html?customer_id=NS10000?beginDate=2016-01-01?endDate=2016-02-26

This works, but I always have to enter the server username and password. Is there a way I can bypass the authentication or do it within the link without the username and password being visible in the url?
