🔐 SimpleLock

SimpleLock is a lightweight and secure server-lock plugin for Paper servers. It allows server administrators to temporarily lock their server behind a randomly generated numerical access code.

Perfect for private servers, development servers, testing environments, maintenance periods, or situations where you want to temporarily restrict access without shutting down the server.

✨ Features

🔒 Server Lock

Lock your entire server with a simple command:

/lock

When the server is locked, SimpleLock generates a random 6-digit access code.

The code is only shown to authorized administrators and is never revealed to normal players.

🔢 Secure Code Entry

Players joining a locked server are placed into a dedicated code-entry GUI.

They must enter the correct code using the on-screen number buttons before they can access the server.

While locked, players cannot simply bypass the system by:

• Moving around
• Breaking or placing blocks
• Opening inventories
• Interacting with the world
• Using normal commands
• Dropping or picking up items
• Chatting
• Using other common gameplay interactions

👑 Admin Access

Server administrators can continue using the server normally while it is locked.

Authorized admins receive the generated access code and can manage the lock using:

/lock
/unlock

🛡️ Security Features

SimpleLock includes several protections against accidentally or intentionally bypassing the lock:

• Randomly generated access codes
• Configurable maximum attempts
• Optional kick/block action after too many failed attempts
• UUID-based player authentication
• GUI interaction protection
• Protection against inventory exploits
• Code is not displayed to normal players
• Code is not exposed through tab completion
• Lock state can optionally persist through server restarts

⚙️ Highly Configurable

SimpleLock is designed to be easy to customize.

Configuration options include:

• Lock persistence
• Code length
• Maximum attempts
• Failed-attempt actions
• Temporary block duration
