Now that I am using iOS more thanks to my recent purchase of an iPad Mini, I am constantly being reminded of the restrictions if poses.  A perfect example is the difference in using LastPass with Android and iOS. 

With Android, LastPass runs in the background and detects whether an app or web page with login screen has appeared, and when it does, a dialog appears prompting the user to login to LastPass. The app is also capable of detecting which app or web site you are using so that the proper one is displayed as an option for AutoFill or to copy your credentials for pasting on the login screen. When combined with a finger print scanner, the process of using LastPass to enter credentials on Android is fast and easy.

LastPass does not run in the background on iOS and therefore has no way to see whether you are in an app or web page that is prompting you for credentials. If you have to manually task switch or start the LastPass app, login to LastPass, copy the credentials (one at a time for userid and password), then manually paste on the login screen. While the process provides for access to your credentials, it is not nearly as easy or fast to use as with Android.

To be fair to iOS, the same issue occurs with Windows 10 store apps, although the LastPass Chrome extension runs on my Surface 3 and therefore detects and can autofill login credentials for web pages.

One will point out that iOS not allowing for apps to monitor what is displayed on your screen is a security and privacy feature, but one that in my opinion makes the mobile experience harder. LastPass requires I provide credentials to access the information I store in it, why shouldn't I be able to specify to iOS that I want it to monitor and prompt to provide quick access to my credentials?
