How to save the password for captive protals?

[klopara]

I am currently living in a dorm and a captive portal login page is displayed every time I want to join the dorm's network. The problem is that when the page is displayed and I put in my login credentials, Safari (or whichever app is responsible) doesn't offer me a chance to save the login information and I have to type it manually every time.
I have tried tinckering with Safari's options but that didn't help at all.
Did anybody encounter a similiar problem? How do I fix this?

P.S. I am using iPhone 5c with iOS 8.3.

Go to the WiFi section of your Settings app and find the WiFi network that you are using there and see if there is a little blue "i" in a circle icon. If there is tap on that and see what options are offered there--often there are auto-join and auto-login options that are present that could perhaps help with this.
