what is admin_data.txt?

[amunizp]

Is it the admin password?

Is the idea that it is OK to have this as txt and not hashed because it will be behind a firewall? And only server admins have access to it?

admin_data.txt holds a hashed password for the member detailed in person_data.txt. This creates a single member who is an admin with the name rml and the password rml.

This is because you need an admin to appoint another admin. Once a regular member is appointed admin by rml, the identity rml can be deleted or the password for rml can be strengthened.
