What feature do you want to see added?

I'd like there to be a config toggle for the "You own x accounts" message.

Are there any alternatives?

I haven't found an alternative to this idea.

Anything else?

I personally don't think checking IPv4 addresses yields enough useful information for how annoying this feature is. I'd really like the ability to disable it.

If you don't give the permission authme.player.seeownaccounts to your players, they will not see this message
