Pass login credentials in IRPT page in SAP MII 12.2

Hi,

I have created an irpt page which I have assigned to an activity in SAP ME. But Everytime I start the activity I have to input my login credentials in MII to be able to see that page. Is there a way to pass them in the external URL or through activity manager so that I dont have to login every time I call this page?

Thanks
