Getting Started

Welcome to Tech City Bank

The Tech City Bank (TCB) demo is an example of how a bank can integrate MIRACL Trust® into their mobile and web 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 both into a mobile application and into a web application (from the mobile 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 website on a shared un-trusted desktop browser

What you need to run the TCB demo:

  • A computer (to open a web page with a browser)
  • A working email address
  • Five minutes
  • A smartphone (to run an Android or iPhone app)

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.
