Adding shared players to Lunar Client means creating accounts that multiple people on your home network can use to join the same Minecraft server or world together
Lunar Client is a third-party launcher that modifies how Minecraft looks and plays — it adds performance tweaks, visual mods, and settings that the standard launcher doesn't include. When you want multiple people on your network to play together through Lunar Client, you need to set up shared accounts or configure the launcher so each person can log in with their own Minecraft account. The method depends on whether you want everyone using one account or each person using separate accounts.
The fastest way is to add each player's Minecraft account to Lunar Client on the same computer, then let them log in when it's their turn. If you want people playing simultaneously from different devices on your network, each device needs its own Lunar Client installation with that person's account added to it.
Key Takeaways
- Lunar Client stores login information locally, so adding a second account means installing the launcher on the same computer and signing in with that account's credentials.
- Multiple people can play at the same time only if each person has Lunar Client installed on their own device or if you set up separate user profiles on the same computer.
- Lunar Client remembers which account you last used, so switching between players on one computer requires logging out and logging back in each time.
- Mods and settings in Lunar Client are tied to each account, so different players may see different visual effects or performance settings depending on what was configured for their login.
Adding a Second Account to Lunar Client on One Computer
Open Lunar Client and look at the login screen. If you are already logged in, click the account name or profile icon in the top right corner, then select "Log Out" or "Switch Account." This takes you back to the login screen where you can enter a different Minecraft account's username and password.
Type in the second player's Minecraft username and password, then click "Play." Lunar Client will verify the account with Minecraft's servers and log that person in. The next time someone opens Lunar Client on that computer, it will remember the last account used — so the first player will need to log out again to let the second player in.
This method works for turn-based play where people take shifts on the same computer. It does not work for simultaneous play, because only one person can be logged into Lunar Client at a time on a single installation.
Setting Up Separate Accounts on Different Computers
If you want multiple players to join the same server at the same time from different computers on your network, install Lunar Client on each computer. read the installer from the official Lunar Client website on each device, run the setup, and complete the installation.
Once installed, each person logs into Lunar Client with their own Minecraft account on their own computer. They can then join the same server or world simultaneously. Each installation keeps its own settings, mods, and login information separate, so one person's graphics settings or mod choices will not affect what another person sees.
Make sure each computer has enough disk space — Lunar Client typically uses 2 to 4 gigabytes, plus additional space for Minecraft worlds and mods if you install them.
Using Windows User Profiles for Multiple Players on One Computer
If you have one computer but want to avoid logging in and out repeatedly, create separate Windows user accounts for each player. Each Windows account can have its own Lunar Client installation with its own login, and switching between them does not require logging out of the launcher.
Go to Settings, then Accounts, then "Other people." Click "Add account" and follow the prompts to create a new Windows user. Once the account exists, have the second player log into Windows using their new account, then install and open Lunar Client. They log in with their Minecraft credentials, and their settings are saved to that Windows profile.
When the first player wants to play again, they switch Windows users (using the Start menu or Ctrl+Alt+Delete), and Lunar Client opens with their account already logged in. This avoids the need to log out and back in within the launcher itself.
Connecting to the Same Server or World
Once all players are logged into Lunar Client on their respective computers or accounts, they can join the same server by entering the server address in the multiplayer menu. If you are running a local server on your home network, use the local IP address of the computer hosting the server — typically something like 192.168.1.X — rather than an external address.
To find your server's local IP address, open Command Prompt on the server computer and type ipconfig. Look for "IPv4 Address" under your network adapter. Share this address with other players, and they can enter it in Lunar Client's "Direct Connection" field to join.
If you are connecting to a public server outside your network, all players enter the same server address regardless of which computer they are using. Lunar Client will connect through the internet just as the standard Minecraft launcher would.
Troubleshooting Login and Account Issues
If Lunar Client says an account is invalid or the password is wrong, double-check that you are using the correct Minecraft username, not the display name. Minecraft usernames are case-sensitive, and spaces or special characters must match exactly. If you have changed your password recently, make sure you are using the new password, not the old one.
If Lunar Client logs you out unexpectedly or says the session has expired, your internet connection may have dropped briefly. Close Lunar Client completely, wait a few seconds, and open it again. Log in with the account credentials. If this happens repeatedly, restart your router and try again.
If one player can log in but another cannot on the same computer, make sure you are actually logging out before trying the second account. Look for a logout button or account switcher — it is usually in the top right corner of the launcher window. straightforward closing the launcher and reopening it will not log you out; it will log the same account back in.
Managing Mods and Settings Across Multiple Accounts
Each account in Lunar Client has its own set of installed mods and settings. If you want all players to see the same visual effects or performance tweaks, you need to install the same mods on each account. This means logging into each account separately and installing mods through Lunar Client's mod menu.
Some mods are account-specific because they store personal data like keybinds or cosmetics. Other mods are purely visual and will look the same regardless of who is logged in. Check the mod description in Lunar Client to see whether it is account-dependent.
If you want to copy settings from one account to another, there is no built-in export feature in Lunar Client. You will need to manually configure each account's settings, or use separate Windows user profiles so each player's settings stay isolated and do not interfere with each other.
Frequently Asked Questions
Can two people play on the same Lunar Client account at the same time?
No. Only one person can be logged into a single Lunar Client account at a time. If two people try to log in with the same account simultaneously from different computers, the second login will disconnect the first. Each person needs either their own Minecraft account or their own computer with a separate Lunar Client installation.
Do I need a separate Minecraft account for each player?
Yes, if you want multiple people to play simultaneously. Minecraft accounts are tied to individual players, and only one person can be logged in per account at a time. If people are taking turns on the same computer, they can share one account, but simultaneous play requires separate accounts.
Will mods I install on one account show up on another account?
No. Mods are installed per account in Lunar Client. If you want all players to use the same mods, you need to install them on each account separately. This applies whether accounts are on the same computer or different computers.
What is the local IP address, and why do I need it?
The local IP address is the internal address your computer has on your home network — something like 192.168.1.5. You need it so other computers on your network can find and connect to a Minecraft server running on your computer. External servers do not need this; you just use the server address provided by the server owner.
Can I play on a public server with multiple accounts from the same computer?
Yes, but only one at a time. You log out of one account, log in with another, and join the server. Public servers do not care which account you use or how many accounts you have — they just see one player per login session.
