Apple Watchs diminutive screens have made conventional alphanumeric passwords impractical. Apple Watches dont require or even allow – their wearer to log in, and feature a reset button that allows anyone with possession of the device to wipe its data and settings and claim it as their own.

The solution, for now, is two factor technology that sends a simple numeric code to a mobile device that can then be entered into a traditional login screen.”]
