LoginSecurity Icon



LoginSecurity is a lightweight password authorization plugin. You can optionally set a password each time you enter the server, adding a double layer of security to your account. The password is stored inside the configuration file, nobody else except the server owner can access or modify it.

How does it work?

Install the pluign to your /plugins/ directory, then start your server.
Type /register <password>, your account is now locked with a password.
For each time you login, make sure to use /login <password>.


  • Register your account optional or required (change in config)
  • 5 useful commands to manage your password
  • Saving supported in SQLite and MySQL
  • Encryption available in: MD5, SHA, SHA-1, SHA-256, SHA-512 and PHPBB3
  • Custom encoder: UTF-8 and UTF-16
  • Customizeable login session
  • Customizeable login timeout
  • Custom min and max length for passwords
  • Messager API for client mods
  • User friendly experiance
  • Converter for xAuth (detects if xAuth is installed)
  • Easy to use
  • Blocks anything from happening before logged in (commands, movement ,etc.)
  • Supports blindness effect for login
  • Prevents being kicked by orther players loging in with your name

Session login allows the user to log in right after they logged out and not have to type in their password again. (1 minute time limit of being logged out, stores IP during that time to keep everything safe)


/lac - Admin command, rmpass and reload

/register <password> - Set your password

/rmpass - Removes your password

/login <password> - Login with your password

/changepass <old> <new> - change your password

/logout - Logout


  • ls.admin - allows admin command

This plugin is connecting to mojang services to conver old data to new UUID data. It sends a request for every single player stored in your database, wich only hapends if you upgrade from 2.0.8 or lower to 2.0.9 or higher. This plugin utilises Hidendra's plugin metrics system, which means that the following information is collected and sent to mcstats.org:

  • A unique identifier
  • The server's version of Java
  • Whether the server is in offline or online mode
  • The plugin's version
  • The server's version
  • The OS version/name and architecture
  • The core count for the CPU
  • The number of players online
  • The Metrics version Opting out of this service can be done by editing plugins/Plugin Metrics/config.yml and changing opt-out to true.

    Hello, First of all, congratulations for your wonderful plugin. I'm currently with the 2.0.8 version of login security but with version 2.0.9, the conversion uuid will not work. You can see the logs here: http://pastebin.com/xqt4xA8B Can you fix this problem please ? Thank you in advance!

    People can use your permissions by changing your name's capital letters (Server owner is Mark, but a hacker can use name MarK or mark to use his permissions)

    @AvengeR9966: Go

    they hacked your account

    bij using a capital letter in the name

    so if your name is Nick

    someone can hack your account bij using a cracked clint en make a his name NICK or NiCk or NIck or ....

    this is somthing why this plugin does not work on MultiCraft or Linux servers on Windows this hack doesnt work

    look at the users who logget in on your server. if there are people with capital letters in the names

    @tennya: Go

    Tennya, I already set the MySQL settings to "true" and it made a table called "ls_users". But when I player tries to register with password, the console displays error and MySQL table is still empty without any information.
