Using a PIN -Personal / (or sometimes, Private) Identification Number- is an additional security factor for transactions and serves as a simple way to add an extra layer of authentication or access management. A PIN is usually made up of a few (4-6) numeric digits that are easy to remember. And generally a PASSWORD and a PIN are used together: the password being to initiate an operation (access an application) and the PIN to authorize various operations within the application. This example shows how to use a PIN without using your device's numeric virtual keypad. That is, the example provided here is in its nature indicated for use on mobile. However, it can be used in the same way for Desktop, but I don't think it would make much sense.
