Different Accounts
I noticed that when someone logs in with a second account, the server links the two accounts via the IP address. In my opinion, this is somewhat problematic, because what happens if multiple people live in the same household or if someone changes networks? In that case, the information would be lost again. It would be good if players could manage or edit this information themselves.
Where exactly is the problem? Are you having problems logging into other accounts?
It’s not really a problem – more of a possible improvement.
For example, I once joined the server with an account and registered. Later I changed my account name, but now the old name is permanently linked to my IP address and I have no way to edit or update it. It would be helpful if players could manage or modify this information themselves.
