In iOS 11 they have introduced password autofill which fills the username and password in iOS app like the same way it does in Safari, User goes to website first, logged in save the username and password in keychain and then open app were the fields are automatically populated, the username and password
can it be implemented in other ways, like I logged in the app first and then while going on the website through Safari it automatically fills the username and password?
Is there any documentation or articles regarding it?
