I have one iPhone running iOS 9 and another iPhone running iOS 11.
On the iOS 9 iPhone, I can navigate to http://username:firstname.lastname@example.org in Safari, and the webpage will pull up without asking for my username and password. I can then add this full URL to my Home Screen as a direct shortcut.
On the iOS 11 iPhone, when I navigate to http://username:email@example.com, I am automatically redirected to http://mywebsite.com. I have to manually type my username and password in the pop-up form, no matter what. I cannot add http://username:firstname.lastname@example.org to my Home Screen because the URL is always changed to http://mywebsite.com. It seems that there is no way to edit or customize the URL of a Home Screen shortcut.
For my iOS 11 iPhone, is it possible to embed my website's username and password in the URL itself, so that I can add this URL to my iPhone's Home Screen, so I will never need to type in my username and password manually?
I understand that embedding the password in the URL may not be very safe, but this is not a "high security" application, so convenience is more important than high security in this case.
If the answer is no, can you suggest a way that I can re-write my website to produce the same effect, without relying on cookies? I cannot rely on cookies because the way that my website works is that it can't place any cookies. Maybe via PHP? I know this question would be a web design question and not an Apple Product question.
TL;DR: My aim is to hard-code a username and password in a URL somehow, so that I never have to manually type in my credentials in iOS 11.
