SkinVault
One plugin for login + skins. Authentication and skin restoration for servers running in offline mode, including mixed online-mode / offline-mode setups.
Features
Premium auto-login
Mojang-authenticated (premium) players are logged in automatically — no password prompt. They keep their real skin.
Offline-mode password auth — native pre-world screen
Offline-mode players authenticate on a native password screen shown before the world loads. No chat commands, no GUI hacks, no fake inventory menus.
- Register: two password fields (password + confirm)
- Login: one password field
- All on-screen text is editable in
config.yml
Impostor protection
If an offline-mode player tries to join with a username that belongs to a real premium account, they are kicked. Premium names stay reserved for their owners.
Sessions
Reconnecting from the same IP within a configurable window skips the password prompt entirely.
Built-in skin restoration
- Offline-mode players automatically receive the skin associated with their own username if a matching account exists.
/skin <name>— set your skin to another account's skin./skin <player> <name>— admins can set another player's skin.- Applied skins are saved per account and re-applied on every join.
