Users

Enable or disable Home Assistant user accounts on a schedule or condition: house-sitter logins, rental-guest accounts, kids’ accounts after bedtime.

You cannot lock yourself out: disable_user refuses owner accounts and system-generated users, so no automation, prompt, or typo can take the owner’s access away.

Find user_id values with the MCP get_registry tool (users) from the terminal, or in Settings → People.
