insert username and password with querystring?

[myssing]

I'm using graphs from my Zabbix solution and displaying them in iframes in other personal tool. This gives me control of which graphs to load and "automatically" resize on window resize events.

But i'm struggling with bypassing the Zabbix login prompt.
Is it possible to send my credentials like username and password with querystring to zabbix, to get passed the login prompt?

As far as I know it's a post request.
Try to trace the login operations with something like 'Live HTTP Headers' for Firefox.
