Password doesn't update on wi-fi connection webpage
I have an iPad 4th Gen and an iPhone 5s which I bring to as use at work, where I connect to the company wifi.
The devices don't connect to the company wi-fi directly, but need to be manually selected everyday. When the network is selected, a web-page is thrown up to enter my credentials. We need to change the passwords every 45 days, but when I enter in the new password, and submit, I am not presented with the usual dialogue whcih asks me if I want update the Keychain entry.
Is there any way to update the password, so that it gets autofilled?
