passbook is an open-source Identity Provider focused on flexibility and versatility. You can use passbook in an existing environment to add support for new protocols. passbook is also a great solution for implementing signup/recovery/etc in your application, so you don't have to deal with it.
For bigger setups, there is a Helm Chart in the `helm/` directory. This is documented [here](https://passbook.beryju.org/docs/installation/kubernetes/)
To develop on passbook, you need a system with Python 3.8+ (3.9 is recommended). passbook uses [pipenv](https://pipenv.pypa.io/en/latest/) for managing dependencies.
Since passbook uses PostgreSQL-specific fields, you also need a local PostgreSQL instance to develop. passbook also uses redis for caching and message queueing.
For these databases you can use [Postgres.app](https://postgresapp.com/) and [Redis.app](https://jpadilla.github.io/redisapp/) on macOS or use it the docker-compose file in `scripts/docker-compose.yml`.
