iPhones have Touch ID and it works brilliantly and with little drama. Samsung introduced a finger print scanner with the S5, but it is not even close to the ease of iOS. It is cumbersome and can take several attempts to get it to work.

So, in a few months time, iOS 8 will be made public, and one of the new APIs is around the Touch ID.

A third-party app called 1Password is a digital vault for storing all of your web logins and sensitive data.

1Password for iOS 8 is already in beta, and has taken advantage of Touch ID and the ability to directly integrate with Safari. The result is a frictionless experience using Touch ID to authenticate without entering your password.

This way of working is classic genius and simplicity.
