Safari's password and auto fill feature is fantastic. It saved you all the trouble to fen enter user name and password all the time. However, there is a catch. When you enable this feature, it asks you to set passcode for the iDevices. This is to prevent other takes your iPad, unlock it and see your saved password. However, if you let your family member, friends use your iPad, you need unlock the devices for them. They take the device and they can easily go to settings, go to Safari and looking at all my saved password without reentering password! iTunes and iTunes Store asked you renter password every 15 minutes, I do not know why this is any different. I really hope Apple fix this. Solution is simple, when user tries go to Safari's setting and visit password and refill section, they need enter the password. Without the password iOS should refuse anyone looking that section.
