Getting Started

Welcome to our Tech City Bank App

The Tech City Bank (TCB) app demo is an example of how a bank can integrate MIRACL Trust® into their iOS or Google Play applications while meeting the "strong authentication" requirement for PSD2.  It provides an end-user scenario for downloading, activating and using MIRACL Trust® to securely authenticate into an app.


There are multiple user scenarios with which you can use MIRACL Trust for signing in, so in this demo instance, please follow the instructions for this scenario:

“A user wants to login to a mobile app on a mobile or tablet

What you need to run the TCB demo:

  • A smartphone (to run an Android or iPhone app)
  • A working email address
  • Two minutes

Note that the Tech City Bank demo site allows anyone to register and log in.  In a real world scenario, such a site would typically also perform authorisation and would only allow known users to log in.
