[smartive](https://smartive.ch/) replaced the existing backend of the bin mobile app for the [bin cooperative’s eLearning platform](https://www.bin.ch/de/leistungen/elearning.html). The app makes teaching materials and books digitally available to apprentices and simplifies teaching thanks to sophisticated tools like highlighting and drawing. They integrated ZITADEL for authentication and authorization to rely on established standards, which saved them at least two weeks of initial development time and even more in maintenance.

## Key outcomes

- Migrated five thousand users to ZITADEL
- Full integration within eight hours
- Predictable pricing independent of user count

## Challenge

smartive had to replace an existing backend, because it was outdated and didn’t rely on standards. The goal was to implement the same functionality as before. Using state of the art technologies and to rely on standards wherever possible was the main focus. Using an external IAM solution was the right choice to minimize development impact. The migration process must be as smooth as possible, because most students already used the first version of the app.

## Solution

In ZITADEL the bin app has one organization that contains projects for the development and productive environment. All the users are managed by the bin organization which means that they have a @bin.ch account for their login. Since these users already existed in the previous system they had to be migrated to ZITADEL.
The books a student is allowed to use are controlled by roles defined on the project and assigned to the user.

Implementing the migration process that imported all users into ZITADEL was an easy task, as the ZITADEL API was straightforward to use. Because ZITADEL follows the API first approach, all the data from the existing system could be migrated with a migration script that was executed once for each environment.

## Result

Right in time for the new semester, smartive was able to deliver the new app. With the integration of an existing IAM instead of a custom implementation they saved several weeks in development time and even more in maintenance. The predictable pricing, independent of user count, and the fast feedback from ZITADEL support contributed to the success of the project.

## Future Plans

smartive is currently working on an extension, such that the bin app becomes a platform for multiple publishers. With multi-tenancy out of the box, ZITADEL is still the perfect match for their future endeavors.
