Autologin

The autologin buildable signs you in automatically, so the login screen is skipped. It’s compiled in at build time, and the account it signs in with comes from environment variables at runtime. Use it for local development, CI, or demos.

Caution

Never expose an autologin build to the internet or any untrusted network. Anyone who can reach it is signed in as that account. Arcane logs a warning at startup when autologin is enabled.

Enable autologin

1. Build Arcane with the buildables tag and autologin in EnabledFeatures. See Buildables.
2. Set the credentials of an existing local user on the container:

environment:
  - AUTO_LOGIN_USERNAME=arcane
  - AUTO_LOGIN_PASSWORD=arcane-admin

When the frontend loads, Arcane signs in with these credentials. Autologin turns itself off if local authentication is disabled.

Reference

Variable	Default	Description
AUTO_LOGIN_USERNAME	arcane	Username to sign in as.
AUTO_LOGIN_PASSWORD	arcane-admin	Password for that user. Supports AUTO_LOGIN_PASSWORD_FILE to read it from a file, such as a Docker secret.
