PinPrompt is a security plugin that adds two-factor authentication (2FA) to your server. You can force and/or allow players to use a PIN to login, this adds an extra layer of protection on players accounts and especially staff accounts from third parties that don't know the PIN.

Amazing plugin to give you peace of mind about your staff and also help players that share PCs.

Force staff members to have a PIN or/and allow normal players to create their own if they want.

This plugin is NOT meant to be used on Cracked server for use such as an Auth system, it simply aids in securing player/staff accounts on online servers/networks.

  • Config settings such as attempts allowed, time to enter, head theme, event blocking, messages, sounds and more!
  • SQLite & MySQL support, sync your player's pins across multiple servers (Bungeecord network).
  • Brute force protection, Limit the time a player has to enter their pin, the maximum amount of attempts they have and even temporally ban them for too many incorrect attempts.
  • Developer API. The plugin currently has some API events for you to spice things up if needed. PinCreationEvent, PinBlackListedEvent, PinCorrectEvent and PinIncorrectEvent.
  • Changeable PIN length, have up to 43,046,721 combinations of PINs for you to use, which would take over 20 years to crack if you entered a PIN every 15 seconds.
  • Regular plugin updates with bug fixes
  • Permission-based so you can force everyone to use a PIN or only certain players like staff members or even just yourself.
  • Head Themes. Change your PIN number heads to many different themes including Quartz, Pumpkins, Bloody, Advent and more! Fun for any time of year!
  • Single inventory without cursor issues. Other plugins use different inventories for each step of entering your PIN and will reset your cursor to the centre of the screen which is very annoying and frustrating. PinPrompt doesn't and only updates the title of the inventory with special packets sent to the client.
  • Sessions. Make players only have to login every X hours and optionally only using the same IP used to start the session!
  • Block inputs that can naturally bypass GUIs such as hacked clients, including but not limited to, Moving, Interacting, Chat, Commands. You can also block entity targetting and damage so the player can't die when entering their PIN.
  • Highly efficient with performance in mind since the start and highly optimized, if you see any timings/heap reports with PinPrompt being an issue, send me over the information and I will do my best.
  • Hex colors in supported Minecraft versions. (1.16+)
  • Supports all popular versions. This means you can use this on 1.8, 1.12, 1.18 or anything in between with support for future versions as they come!
  • AuthMe. Compatible with AuthMe as an extra pin option after the user enters their password.
  • Spectator Support. Support to change spectator mode players into another gamemode to enter their PIN since you cannot click anything in that gamemode.
  • Safety Net. The plugin will stop players from joining if it has issues connecting to the database.
  • and many more...

How to install:

Spigot/Paper or any fork:

Simply drop and drag the plugin's jar into the plugins folder of your server, feel free to edit the config.yml to fit your needs then make sure to give the permissions you want to your groups.
Bungeecord/Waterfall network or any fork:
Do the above install steps for each sub-server on your network OR make a new server just for PinPrompt and once they enter their pin they can be sent to another server (Is in the config) (Recommended) OR simply only install it on your hub server if you force all joins to that before anything else, I highly recommend using a MySQL database so you can connect all the plugin instances together and use the same database.
