# Sign up / Guest account

The Online Services can be used as a guest (without creating a user account) or as a registered user. Please note that as a guest, you may not have access to all services, as some airports require a verified email address and a billing address. If you use the Online Services regularly, it is recommended to create a user account. You can then also create templates and profiles to process requests more efficiently.
