PassiveWhitelist is a lightweight plugin designed for semi-private Minecraft servers, such as school or small friend groups, where server access needs to be restricted to trusted players. Instead of traditional whitelisting, new players must answer a security question on their first login. Once they answer correctly, they are permanently authenticated and can freely interact with the server. The plugin is highly configurable, allowing server administrators to customize the security question, messages, and time limits.

Usage:

1. Installation and Setup:
   • Place the downloaded PassiveWhitelist plugin JAR file into your server's plugins folder.
   • Start the server or run the /restart command.
2. Configuration:
   • The plugin uses a customizable configuration file located at plugins/PassiveWhitelist/config.yml. Below are the default settings:
     • answer: "16"
       
     • question: "Evaluate the definite integral of four with respect to x, from zero to four."
     • welcomeMessage: "Welcome! Please answer the following question to join the server:"
     • correctMessage: "Correct! You can now play on the server."
     • incorrectMessage: "Incorrect answer. Please try again."
     • kickMessage: "You didn’t respond within the time limit."
     • kickDelay: 3
     Each of these values can be customized to suit your server's needs. For example, you can change the question, correct answer, or time delay before unverified players are kicked.
3. Reload:
   • After modifying config.yml, use /pw reload to apply changes without restarting the server.

Commands:

• /pw reload: Reloads the plugin's config.yml dynamically.
• /pw revoke <player>: Revokes authentication for a player, requiring them to answer the question again.
