SecPlayer

Players register once, then authenticate on every later join before they can move or play. An OP-only admin panel holds the approval settings, with an optional approval mode for new registrations, plus timezone grouping and the ability to approve or deny player profiles.

Each player manages a profile where password, email and account deletion can be handled. Changes trigger an email notification, and a disconnect follows where the mod requires it. Display name support lets players set an in-game name with spaces through the secplayer setAlt commands, and setting a name automatically switches the player to that in-game name when registration is not enabled.

The login logo is sent by the server as one image shared by all clients, or configured per client so that each client uses a local image, and it is scaled to fit the panel. Geolocation is optional: country, region and city data come from a GeoLite2-City.mmdb file, and ISP and ASN data from GeoLite2-ASN.mmdb, both placed in the server config folder after obtaining a free MaxMind account. The mod targets Forge 1.18.2 and is installed in the mods folder of both server and client. Single-player and the integrated server use the registration flow as well.
