If you have an iPhone 6 Plus or iPhone 6, you get to experience a few perks that people with older iPhone models don't have. One is a bigger screen and many apps that take advantage of it. Another is the Touch ID fingerprint scanner (iPhone 5S owners get this benefit, too), which can add a layer of protection to apps that contain sensitive data, like the personal finance app Mint. You can also use Touch ID with one of our favorite password managers, LastPass, to log you into all your other accounts without having to type passwords.
