### Advanced, Secure, and Fully Customizable Authentication<\/p>\n
**LoginSystem** is a modern, high-performance authentication plugin designed from the ground up to maximize your server’s security. Tired of old and clunky plugins? LoginSystem will add a professional touch to your server with its **multi-database support**, **advanced hashing options**, and **fully translatable structure**.<\/p>\n
All database operations run **asynchronously**, meaning your server will not experience any lag.<\/p>\n
**Wide Database Support:** SQLite, H2, MySQL, MariaDB, PostgreSQL, and even MongoDB!<\/p>\n
**Top-Tier Security:** SHA256 hashing by default, automatic migration from legacy algorithms (SHA1, MD5, etc.), and unsafe password prevention.<\/p>\n
**100% Translatable:** All messages are managed through language files. New languages can be downloaded automatically from GitHub.<\/p>\n
**Highly Customizable:** Login timeout, registration limit per IP, movement\/chat\/command restrictions before login, and much more.<\/p>\n
**Admin Commands:** Many useful commands like force-registering players, changing passwords, unregistering accounts, and reloading the plugin.<\/p>\n
**Developer API:** A powerful API that allows other plugins to integrate with LoginSystem.<\/p>\n
**Automatic Update Checker:** Checks for new versions on SpigotMC (Resource ID: 74894) and notifies admins.<\/p>\n
**GUI Support:** The API allows for the creation of modern Anvil GUI login screens instead of using chat.<\/p>\n

\nLoginSystem provides a powerful **v2 API** to facilitate integration with other plugins.
\n# API Example
\nAccessing the API:
\n“`java
\nLoginSystemAPI api = LoginSystem.getApi();
\n“`
\nChecking if a player is logged in:
\n“`java
\nif (api.isLoggedIn(player)) {
\n \/\/ …
\n}
\n“`
\nListening for a successful login event:
\n“`java
\nimport me.bartuabihd.loginsystem.api.v2.event.LoginEvent;<\/p>\n
\npublic void onPlayerAuthLogin(LoginEvent event) {
\n Player player = event.getPlayer();
\n player.sendMessage(“Welcome back via API!”);
\n}
