How to Make Your DayZ Server Private With a Password

Make a DayZ server private by setting the non-empty password value in the active configuration, then applying the change. This guide covers self-hosted PC, managed hosting, console servers, credential security, and troubleshooting.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Set the player join password in the active DayZ server configuration: password = "Use-a-long-unique-passphrase";. On a self-hosted PC server, edit the file named by the -config launch parameter (often serverDZ.cfg), save it, and complete your setup’s restart or apply procedure. Managed hosts expose the same setting in a control panel or configuration editor. Console servers are rented and administered through a hosting provider, where a password can restrict access.

What makes a DayZ server private

A DayZ join password requires a player to enter the correct password before the server accepts the connection. It is a shared secret: everyone you intend to admit uses the same value, and anyone who does not know it should be refused at the connection stage.

The setting that controls ordinary player access is named password. In the official DayZ configuration reference, it appears as:

password = ""; // Password to connect to the server

Replace the empty value with a long, unique passphrase. The quotation marks and semicolon are part of the configuration syntax. Do not paste a real password into a public guide, screenshot, stream overlay, log, or support ticket.

A password is useful for a friends-only session, a scheduled community event, or a development server that is not ready for public players. It does not turn the server into a complete identity-based access system. Anyone who receives the shared password can normally pass the same join check until you change it.

The three DayZ credentials you must keep separate

Credential Purpose Where it belongs Who should receive it
password Lets an ordinary player connect to the server. The active DayZ server configuration file. Only players you intend to admit.
passwordAdmin Lets a user become a DayZ server administrator. The active DayZ server configuration file, as a separate setting. Trusted administrators only.
RConPassword Authenticates BattlEye remote-console administration. The BattlEye configuration, not the main join-password line. People who genuinely need remote administration.

The most common configuration error is changing passwordAdmin while expecting to restrict player joins. That value does not replace the player password. Likewise, placing a BattlEye RConPassword in the DayZ join-password field will not create the access control you want. Treat all three as different secrets with different risks.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Before you edit anything

  • Identify your hosting model. The procedure differs between a PC server whose files you control, a managed PC server, and a console server rented through a provider.
  • Find the active configuration name. DayZ uses the file specified by the server’s -config launch parameter. serverDZ.cfg is a common filename, but it is not automatically the active file on every installation.
  • Record your current settings. Make a backup copy before editing so you can restore the previous file if the server fails to start.
  • Choose a passphrase you can rotate. Avoid a password used for email, hosting, administration, or any other service.
  • Plan an application window. The supplied references do not establish one universal hot-reload behavior. Assume that a restart or the host’s documented apply action is required unless your particular setup explicitly says otherwise.

How to password-protect a self-hosted PC server

1. Locate the file selected by -config

Inspect the command, script, shortcut, service definition, or startup manager that launches your DayZ dedicated server. Look for an argument in this form:

-config=serverDZ.cfg

The exact spacing or path can vary. The important point is the filename or path after -config; that is the configuration DayZ reads. If the launch entry points to a custom filename, edit that file instead of assuming the common name.

2. Open the configuration as plain text

Stop the server if your hosting arrangement requires it, then open the selected configuration in a text editor that does not add rich-text formatting. Keep the original file as a backup. Configuration files are sensitive to punctuation, so avoid word processors that may replace quotation marks or alter line endings.

3. Set the player join password

Find the existing password entry. If it is empty, change only its value:

Free tools Windows power users keep installed

One-click scans. No signup required.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
password = "Use-a-long-unique-passphrase";

Use ordinary quotation marks, retain the semicolon, and do not add a second competing password line elsewhere in the file. If the file already contains a non-empty value, replace it rather than appending another line.

4. Check the administrator setting separately

Leave passwordAdmin as a separate line and assign it only to trusted administrators. A player who knows the join password should not automatically receive the administrator credential. Never combine the two values or send them together in a public chat.

5. Save, apply, and restart according to your setup

Save the file without changing its name or extension. Then use the restart, reload, or apply process documented for your server installation. A running process may continue using its already-loaded settings; do not promise players that changing the file alone updates an active server instantly.

6. Verify both sides of the access check

Attempt a connection with the intended password and confirm that the server accepts it. Then attempt a connection without the password, or with an intentionally incorrect value, and confirm that access is refused. Perform this as a controlled check and do not publish the real credential in screenshots or logs.

Using a managed PC host

Managed DayZ hosts generally expose the same underlying setting through a web control panel. The labels vary, but the workflow normally consists of opening the DayZ service, choosing a configuration-file editor or server-settings page, entering a non-empty player password, saving, and pressing the provider’s restart or apply control.

One provider guide describes adding a join password in its DayZ configuration-file editor. Because panel names and button locations change, follow the current instructions for your account rather than relying on an old screenshot. If the panel offers both “server password” and “admin password,” choose the player-facing server password for this task and keep the administrator value private.

If a panel hides the raw configuration, ask support which field maps to DayZ’s password setting. Do not paste an RCon credential into a generic password box unless the panel explicitly identifies it as BattlEye remote-console configuration. After saving, use the panel’s documented restart or apply action and then perform the two connection tests.

Private console servers

Console players do not normally edit a local DayZ dedicated-server configuration file. Bohemia Interactive’s private-console FAQ explains that players rent and administer private servers through a hosting provider and can control access by setting a password. The provider’s current dashboard is therefore the place to create, change, and apply the join password.

Console hosting availability, regional support, account requirements, interface labels, and pricing can change. Confirm those details in the provider account before making a purchase or promising a particular feature to your group. Once the server is provisioned, look for the access, privacy, or server-password control, save the value, and complete the provider’s restart or activation step.

What a password can—and cannot—do

Control How access is decided Best use Limitation
Shared join password Anyone who knows the same secret can attempt to join. Small groups, events, and temporary private sessions. Revocation is broad: changing the password affects everyone.
Whitelist or allowlist Individual player identities are approved. Communities needing per-player control. More administration and a separate setup process.
Ban system Specific players or identifiers are denied. Removing unwanted or disruptive players. It does not, by itself, create a private server.
passwordAdmin A credential grants administrative privileges. Trusted server operators. It is not a player access restriction.
BattlEye RCon password A remote-console client authenticates to BattlEye. Remote administration where configured. It is separate from the DayZ join password.

If one shared secret is sufficient, a join password is the simplest option. If you need to remove one person without changing access for everyone else, investigate a supported whitelist or identity-based access method instead. A password also does not replace moderation, bans, backups, or secure administrator credentials.

Changing or revoking access safely

Rotate the join password

Change the value on the same active configuration or provider panel, save it, and perform the required apply or restart action. Tell the new password only to the players who should retain access. Anyone with the old value should fail the next join attempt once the new setting is active.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Rotate administrator credentials independently

If an administrator or RCon secret was exposed, change that credential in its own configuration area. Do not assume changing the player password also invalidates administrator access; the settings serve different systems.

Keep a distribution list

For a group server, record which channels contain the current join password and remove outdated messages where practical. Avoid posting it in a public community announcement, searchable forum, stream description, or server log.

Troubleshooting: the server still appears public or rejects the password

The password has no effect

  • Confirm that you edited the file named by -config, not a similarly named unused copy.
  • Check that the line is exactly a non-empty password assignment and retains its quotes and semicolon.
  • Save the file, then complete the setup’s restart or apply procedure.
  • Check the startup or service configuration for a different launch profile that points to another file.

Players receive an invalid-password error

  • Have the player retype the current value rather than relying on an old saved entry.
  • Check for leading or trailing spaces, changed capitalization, smart quotation marks, or a password copied with an extra character.
  • Verify that the server actually restarted after the latest change.
  • Confirm that everyone is using the current password after a rotation.

The server will not start after editing

  • Restore the backup to establish whether the edit caused the failure.
  • Compare the changed line with the expected syntax: a quoted value followed by a semicolon.
  • Remove duplicate or accidentally renamed configuration entries.
  • Use the host’s support process if the panel overwrote the file or reports a syntax error.

An administrator can still connect remotely

That may be expected if you changed only the player join password. Review passwordAdmin and the BattlEye RConPassword in their respective configuration areas, and rotate the exposed credential rather than assuming the join-password change covers it.

Self-hosting versus managed hosting

Consideration Self-hosted PC Managed PC hosting Console rental
File and launch-parameter control You control the configuration and the -config launch parameter. The provider may expose a file editor or abstract the setting in a panel. The provider controls the server environment and dashboard.
Setup and maintenance You handle installation, updates, backups, and service operation. The provider handles infrastructure while you manage server settings. The provider supplies the rented console server and its administration tools.
Apply workflow Use your own documented restart or reload process. Use the panel’s save and restart/apply controls. Use the provider’s activation or restart controls.
Platform support PC dedicated-server environment. Depends on the host’s supported DayZ platform. Private console access is tied to the rental provider.
Access-control interface Directly edit password. Configuration editor or server-settings field. Provider dashboard password/privacy setting.
Cost and availability Infrastructure and bandwidth are your responsibility. Recurring hosting terms vary by provider. Regional availability, pricing, and account requirements vary.

Choose self-hosting when direct file and launch control matter and you are comfortable maintaining the service. Choose managed hosting when a provider’s panel and operational support are worth the recurring charge. On console, the rental-provider route is the normal administration path.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Security practices for a private server

  • Use a passphrase that is unique to this server and long enough that guessing is impractical.
  • Do not reuse the join password for passwordAdmin, RCon, hosting, email, or personal accounts.
  • Share the join password through a private channel limited to intended players.
  • Change it when someone outside the group receives it or when the group membership changes.
  • Keep administrator and RCon credentials out of player chat, screenshots, scripts shared with the group, and public repositories.
  • Back up configuration files before edits, but protect backups because they contain secrets.
  • Review access controls separately: a join password does not provide a per-player allowlist, a ban policy, or protection from compromised administrator credentials.

Quick checklist

  1. Identify whether the server is self-hosted PC, managed PC, or console rental.
  2. For self-hosting, read the active filename from the -config launch parameter.
  3. Back up the configuration before editing.
  4. Set password to a unique quoted passphrase followed by a semicolon.
  5. Keep passwordAdmin and BattlEye RConPassword separate.
  6. Save the correct file or panel field.
  7. Restart or apply the change using the documented procedure for your setup.
  8. Test one successful join with the current password and one refused join without it.
  9. Rotate the password if it was shared too widely.

Bottom line

DayZ’s private join control is the password setting in the active server configuration. On PC, follow the -config parameter to the correct file, set a non-empty value, and restart or apply it. On managed or console servers, use the provider’s configuration panel. Keep the join password, passwordAdmin, and BattlEye RCon credentials separate, because each protects a different function.
