If you don’t have a SQL server, you can use SQLite. However please note that this setup will prevent you from running multiple instances of Authelia since the database will be a local file.
Use of this storage provider leaves Authelia stateful. It’s important in highly available scenarios to use one of the other providers, and we highly recommend it in production environments, but this requires you setup an external database.
storage: local: path: /config/db.sqlite3
The path where the SQLite3 database file will be stored. It will be created if the file does not exist.
