Minecraft server security checklist for new owners

Protect the hosting account and admin access

Use a unique password for the hosting account and enable multifactor authentication wherever the provider supports it. Protect the associated email account as well, since password resets often depend on it. Keep recovery codes somewhere accessible to the owner without exposing them to the whole community.

Give co-administrators their own accounts and only the access they need. A builder does not necessarily need billing access, file deletion, or the ability to create other administrators. Review access when a moderator leaves, and rotate shared secrets that person could read. Keep ownership and billing under an account your community can reliably maintain.

Control player access and permissions

For a private server, enable the appropriate allowlist and test that an unlisted normal account cannot enter. Keep the operator list short. Where a permissions system is used, assign narrow roles and test them using a non-operator account instead of assuming an administrator sees the same behavior as everyone else.

For a normal direct-connect Java server, keep account authentication enabled. Do not disable it simply to work around a connection error. Proxy networks have different authentication and forwarding arrangements; follow the proxy’s complete official setup and isolate backend servers so outsiders cannot bypass the intended entry point.

Install trusted software and plan updates

Download plugins and mods from their author’s documented distribution channels. Check the project identity, supported version, and dependencies. A copied file on an unfamiliar download site may not be the same software described by the original developer, even when its filename looks convincing.

Keep an inventory of installed components and remove abandoned experiments through a safe maintenance process. Review updates regularly, make a complete backup, and test changes before applying them to a valued world. Avoid replacing running server files casually; follow the relevant project and host instructions so an update does not leave the process in an inconsistent state.

Keep administrative services private

Expose only the services required for players and your chosen management workflow. If you do not use remote console, leave it disabled. When remote administration is required, use the host’s supported protected connection method and keep its credentials separate from player-facing information.

For a VPS or dedicated machine, configure the firewall and run the game with an unprivileged system account. For shared hosting, ask how the provider isolates administrative endpoints and proxy backends. Copying one firewall command from a guide is not enough when your operating system, ports, or network layout differs.

Prepare for mistakes and account incidents

Keep multiple backup ages and an independent copy of important data. Practice restoring to an isolated instance, including permissions and plugin databases. Store a short incident note explaining who owns the account, how to contact the provider, and where the last tested backup can be found.

If you suspect unauthorized access, preserve relevant logs, restrict access through the host, and rotate affected credentials. Determine which files or settings changed before reopening. A restore can recover a world, but it does not automatically remove a compromised account or fix the permission mistake that allowed the incident.

• Review owners, operators, panel users, and access keys.
• Verify a recent backup can be restored.
• Document the supported route to hosting support.
