Description

First off, in order to make it easier for a user to log in and not have to fully authenticate themselves each time they leave the self-service app, we wanted to enable a 4 digit pin code that could be used to log in to the app (once fully authenticated for a first time). This is pretty standard practice in banking apps.

We didn't want to store that locally since it wouldn't be secure on phones that are rooted.

With that constraint, we need to be able to store this pin on the back-end - then it can also be shared across phones as well.
