With my iPad and iPhone I use the auto fill and remember for password protected sites. I just use my thumbprint to sign in.
I started a thread a week or so back asking if people used a particular password management app but no one had any recommendations. My phone remembers a bunch of my passwords too but it's because they are sync'd from my Google account. I would like to have a 3rd party service that integrates with a thumb print also that stores all my stuff on some non commie server.
