“The first question we asked ourselves was, where do we start? To answer that, we started with the user. We built and tested the product with multiple users and developed multiple prototypes which gave different login options. This initially included Facebook, Twitter, and LinkedIn options. However, after rigorous testing, we realized that having social media login options was not ideal. We needed users to have a complete two-factor authentication and identity check which would allow the product to match them to NHS records. We have now tested this with over 3,000 users.
