## Common questions

### What must I run before starting the full OpenCloud server?

Run the one-time init command with your config folder, data folder, and IDM_ADMIN_PASSWORD. It creates the required configuration, storage folders, and admin account.

### Does OpenCloud need an external database?

No, the backend does not use a database and stores all data in the filesystem. By default, its root directory is $HOME/.opencloud/.

### How are OpenCloud users authenticated?

The backend authenticates users via OpenID Connect. It can use an external identity provider such as Keycloak or the embedded LibreGraph Connect identity provider.

### What should I know about mounted folder permissions?

The host user with UID 1000 has full access to the mounted OpenCloud directories. Any local account with that UID can read, modify, or delete config and data files.
