BahnID Single Sign On

From 2018 to 2021, I worked on the BahnID single sign-on ID service as UX Lead. This service was created in the Digital Lab of Deutsche Bahn AG and is a centralized data management with the Privacy by Default principle. With this ID, users can log in to various Deutsche Bahn services and apps with just one account.

Our challenge

There were many challenges in this project but it were also 3 fun years of ux and design. An aspect which made it challenging but also interesting was the we needed to actively pitch to be integrated into other services, on a constant basis. We also did a lot of cross-product UX work to clearly demonstrate how our product would work in the various services. In no other project have I created so many user flows and constantly incorporated new requirements conceptually. It was definitely challenging to implement so many stakeholder requirements but also a huge learning curve.

Our way to go

Created the sign up/in flows

We had to repeatedly take over the UX work for the DB services which we want to connect with. What does our flow look like with their product? When does the data verification take place, what does the initial registration with BahnID look like in their product?

Built the concept of deletion from scratch

This part was very crucial in terms of data protection and Deutsche Bahn requirements. It was also important to sensitize all stakeholders to the fact that we cannot hide account deletion in a product with the principle of privacy by default.

Visualized all kind of data flows

All kinds of data flows between the various services and systems, which can also be restricted by users. We have visualized complex data models. Also to show how the data is encrypted to meet the high cyber security requirements.

Data management by default

Users initially only have to give an e-mail address. Connected services can request further data, such as name, address, telephone number, etc. The user can also optionally regulate this transfer consents afterwards.

Been part of the design system work

While we were working on BahnID, another team was setting up the higher-level design system. We used this system and also imported our own updates. So there was always a push and pull synchronization.

BahnID been integrated as part of Bahn.de and Navigator

The whole ID product was combined with another project and is now being used as the ID sign in for Bahn.de and Navigator and can still be used as such.

Our achievements

🚀
We successfully launched the product and it went live with Streckenagent.
🔎
We stick to a very minimum personal data set by the users.
💡
We added automatization,  tracking data and user knowledge as benefit.
🖤
I learned so much with this project and am forever thankful for this possibility.
