Create the first administrator
No accounts exist yet in the production database (SQLite (local file)). Create the first administrator account. To prove you operate this deployment, also enter the setup token stored as DASHBOARD_ACCESS_TOKEN in your secrets backend (Infisical) or printed in the server log on first start.
Once an account exists this page disappears. Further accounts are added by an administrator under Users, or with python -m dashboard.manage users add on the server.
