Case study
TRUSTED DEVICE AUTHENTICATION for GM Vehicles
The CHALLENGE
Vehicle tasks in the vehicle, such as account sign in, purchasing, and profile unlock require signing in with a username and password. This creates a major barrier: customers often quit tasks like purchases or signing into MyChevy when asked for credentials, causing very low completion rates.
Tasks such as account authentication, purchasing, and profile unlock require customers to enter a password, pin code, or pattern to authorize.
OUR GOAL: Make authentication painless
Allow customers to use their mobile device to instantly authorize sensitive transactions in the vehicle, avoiding manual password, pin code, and pattern entry.
MY ROLE
I was brought on as lead Product Designer for the project. As lead I was responsible for the end-to-end experience for the platform, working with a team that included a visual designer, content writer, and UX researcher.
DESIGNING AN EXPERIENCE ACROSS MOBILE and VEHICLE
I designed the full end-to-end experience for Trusted Device, which included mobile app and vehicle screens, including the initial setup flow and purchase authentication using Trusted Device. These were done in Axure and a clickable prototype was used to showcase the concept to leadership, as well as for user testing the features.
USER TESTING feedback
I partnered with the UX research team to design a user test to validate our initial concept for the flow. Initial testing found gaps in our instructions, both on the vehicle screen, but also on the mobile app experience.
SERVING AS PRODUCT MANAGER
I served as the Product Manager for the Trusted Device platform. In this capacity, I helped the wider organization understand the platform and find opportunities for using it in many other capacities, such as the implementation of it within our purchase flow on the vehicle.
WORKING CLOSELY WITH ENGINEERING TO UNDERSTAND THE TECHNOLOGY
I worked with the engineering team to learn the technology stack inside and out. This knowledge helped me understand the limits of the technology, but also the opportunities we would have for future products with the Trusted Device as an authentication tool.
building a ROLLOUT of future features
Below is the feature roadmap that I created showcasing the bevy of enhancements we planned to produce over time with the platform.
