Slopes developer Curtis Herbert has been thinking about how to create a better password reset flow for apps on iOS 9 with Universal Links:

With universal links we can remove Safari from that process entirely. Users can now reset their password in-app, allowing the app to also automatically log them in after the reset. This is all possible while still having the security of the reset password email to confirm identity.

Good idea, and one of the many advantages of Universal Links (check out his demo to see how native 1Password integration makes everything easier).
