I set mine up to auto login a particular user on a particular device. Any other device gets a login failure and can bypass that to use the standard home assistant login.
The only thing I can think to do if you want to have your entire network trusted is to trust only part of your network by changing the mask at the end of the IP range (the /32 sets the range to 1 IP address) and then do whatever you need to in terms of IP assignments so that the trusted devices all get IPs in the right range and the untrusted ones don’t.
