Ask HN: Copy passwords to mobile app

Everyone should be interested in secure passwords. But why do mobile app developers still require to manually type in passwords on the device? It's slow and painful if you have special characters and a decent password length. On the desktop we have Keychain, 1Password and in-browser vaults to generate and store a "per website" password. On our handsets we still have to copy+paste from emails, 1password.app one or two times, depending on the login/username complexity.

How do you deal with that problem?
