Consider adding PIN as an option in Identity infrastructure as it is required in most of the projects now.

To facilitate quick login, instead of a password, a user would be allowed to log in with a number-based PIN (which could be 4 digits to 6 digits) for authentication.

It requires additional definition and is repetitive.

So make it available as part of the Identity infrastructure by defining the necessary properties and methods to achieve the same.

### Describe the solution you'd like

* A property to access PIN
* An overloaded method to authenticate users with a PIN instead of a password
* An option to configure the minimum # of digits required to set up the PIN
