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.
To develop on passbook, you need a system with Python 3.7+ (3.8 is recommended). passbook uses [pipenv](https://pipenv.pypa.io/en/latest/) for managing dependencies.
To get started, run
```
python3 -m pip install pipenv
git clone https://github.com/BeryJu/passbook.git
cd passbook
pipenv shell
pipenv sync -d
```
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`.
