# App Domain

The main domain for SquadDNS is used as an **additional security layer**.\
You can set a domain and make sure that only requests through this domain are allowed for the administration.

Please note, to avoid that you lock yourself out, this can only be changed from the **config.yaml** file after the initial setup of the system.
