Saving user name and password on my ipad

[jim-the-tool-man]

I mainly use my iPad with iOS 8.4 when accessing eBay and I know that in the past when I needed to log on that my iPad filled in at least my username if not both my username and password.  NOW each time I log on I have to enter both.  This really gets ridiculous when I click on the eBay link in each email I get from eBay sent about my "saved search items" because even though the "stay logged on box" is checked I have to log on separately for every different email with it's link to a different item.  Is there a way that I can have my iPad save my username and password or at least one out of the two?
