About this project
What does Tiny Auth add?
Tiny Auth

Tiny Auth is a lightweight, modern authentication solution for Minecraft 1.21.6+. Instead of relying on outdated chat-based login commands, it uses a fully immersive Dialog UI that feels like a natural part of the game.
✨ Why Tiny Auth?
Most authentication packs still require players to enter sensitive passwords into the chat. Tiny Auth takes a different approach:
- Fluid Input: Our custom keyboard doesn't reset your mouse to the center every time you click. It's quick, responsive, and smooth to use.
- True Passwords: Create full alphanumeric passwords (A-Z, 0-9) instead of being limited to a simple 4-digit PIN.
- Visual Flair: Includes 35+ built-in themes powered by modern Hex colors.
- Limbo Security: Unauthorized players are placed in a private void dimension. This prevents world-loading lag, blocks "freecam" exploits, and keeps your spawn coordinates hidden.
- Full SFX Suite: Features mechanical click sounds, limit warnings, and a ticking countdown for blocked accounts.
⌨️ Admin Commands
Managing your server's security is straightforward with the built-in function library:
| Command | Description |
|---|---|
/function tiny_auth:auth/admin/bypass {Name:"..."} |
Instantly authorize a specific player. |
/function tiny_auth:auth/admin/logout {Name:"..."} |
Log out a specific player. |
/function tiny_auth:auth/admin/reset {Name:"..."} |
Remove a player's credentials so they can register again. |
/function tiny_auth:auth/admin/reset_all |
Clear the entire database (use with caution!). |
/function tiny_auth:auth/admin/get {Name:"..."} |
Retrieve a user's password (view it with /data get storage tiny_auth:temp get). |
/trigger tinyauth.auth.control_panel |
Open the control panel. |
🎨 Themes & Customization
Tiny Auth supports high-quality Hex colors. Players can switch themes through the in-game UI, or admins can choose a global default.
- Cyberpunk: Bright, high-contrast neon colors.
- Spectrum: A "Zoned" keyboard layout where each row uses a different color.
- Minimalist: Clean, professional grayscale themes.
- Custom: (Experimental) Use
/trigger tinyauth.auth.create_personal_themeto create your own style. Please report any bugs you encounter with the custom UI creator!
❓ FAQ (Frequently Asked Questions)
Why am I in a void world when I join?
- That's our "Limbo" system. It protects the main world and prevents players from seeing your server's secrets before logging in. Once you authenticate, you'll be teleported back to your exact location.
What happens if I forget my password?
- You can use your OTP Code, or an admin can use the
resetcommand to let you register a new password. They can also use thegetcommand to remind you of your existing one.
Does this work with my language?
- Yes! Tiny Auth currently supports English, Spanish, French, German, and Portuguese. The UI automatically adapts to your game's locale.
Will this lag my server?
- No. Tiny Auth is designed with performance in mind and uses
periodic_tickpredicates to ensure timers and UI updates consume almost no CPU resources.
