Panel phpMyAdmin is available here. The access password changes after each server reinstallation, but reinstalling the server does not delete data in the database.

This subdomain automatically supports HTTPS protocol and issues/renews the certificate for you. You don’t need to take care of it yourself. Your application should provide data as HTTP (not HTTPS!). This domain cannot be used for SSH/FTP connections, etc.
