About This Guide
The join password is a password that everyone enters in common when joining the server. If you set one, even those who know the connection address (IP and port number) cannot join without the password.
Set a Join Password
- Open your server in the game panel and open the Startup tab.
- Enter the password you wish to set in the
[SERVER] Join Passwordfield. - Restart the server from the Console tab.

Once the restart is complete, confirm in the connection information displayed in the console that the 参加パスワード (Join password) field shows あり (Yes). You can also check the same field in 接続情報.txt (connection info) in the Files tab.
Operations for Joining Players
When joining players register the server in the game, they should enter the same password in the "Server password:" field.
For the complete connection process, please refer to Project Zomboid - Initial Setup.
Removing the Password
- Clear the
[SERVER] Join Passwordfield in the Startup tab. - Restart the server from the Console tab.
After restarting, if the 参加パスワード (Join password) field in the console shows なし (No), the server is now accessible without a password.
Notes
Direct edits to the configuration file will be reverted
Even if you directly edit Password= in the configuration file (Zomboid/Server/<保存名>.ini), it will be overwritten by the Startup tab values each time the server starts. Always set the join password in the Startup tab.
The 3 passwords are different
| Name | Purpose | Where to set |
|---|---|---|
| Join Password | Everyone enters this to join the server | [SERVER] Join Password in the Startup tab |
| Admin Password | Used to join the server as an administrator | Automatically generated for each server and displayed in the console |
| Account Password | Each player's individual account password for that server | Set by each player themselves when joining for the first time |
About sharing passwords
Share the join password with those you play with using a secure method. Please handle with care as the admin password displayed in the console is also visible to those who have access to the game panel.
