FiveM txAdmin Security: Hardening Your Server Panel With 2FA, Roles and Access Control

Your txadmin security posture matters more than almost any other setting on your FiveM server, because txAdmin is total control. From that one panel an admin can start and stop fxserver, run live console commands, deploy whole server builds, edit configuration, and in many setups reach your database. That makes it the single most valuable target on your box. If an attacker gets into txAdmin they already own the server, without needing to find a vulnerable resource or a leaked database password. This article walks through the practical steps to lock the panel down.

Don’t expose the panel to the open internet

By default the txAdmin web interface listens on port 40120 bound to 0.0.0.0, which means anyone who knows your server’s IP can reach the login page. Bots scan for exactly this. A public login page is a continuous brute-force and credential-stuffing magnet, and it leaks your txAdmin version to anyone probing it.

Pick at least one of these and apply it:

• Put the panel behind a reverse proxy (nginx or Caddy) that terminates TLS, so you reach it over HTTPS on a real hostname instead of a raw IP and port.
• Firewall port 40120 so it only accepts connections from an IP allowlist you control.
• Better still, do not expose it at all: access the panel over a VPN or a private overlay (WireGuard, Tailscale, NetBird), so the management port is never reachable from the public internet.

Note that the game server port (UDP 30120) is separate and does need to be public. Hide the management port, not the server itself.

Strong unique password plus two-factor authentication

Every admin account needs a long, unique password that is not reused anywhere else. That alone is not enough. Turn on two-factor authentication for every admin so a stolen or guessed password cannot log in by itself. txAdmin supports TOTP authenticator apps and passkeys; enroll a second factor the moment an account is created, before that admin gets any real permissions.

If you support local accounts rather than Cfx.re-linked logins, 2FA is non-negotiable, because a local password is the only barrier in front of full server control.

Least privilege with per-admin permissions

txAdmin stores admins and their permissions in admins.json, managed through the admin manager in the panel. The common mistake is giving everyone “all permissions” because it is easy. Do not. Most of your team does not need to restart fxserver or open the live console.

• Give moderators only what they need: player management, kicks, bans, warnings.
• Reserve console access, the deployer, server start/stop, and settings to a small group of senior, trusted admins.
• Keep the master account for yourself and use named per-person admin accounts for everyone else, so actions are traceable to a person.

Separating who can touch the live console from who can only moderate limits the blast radius when an account is compromised or an admin goes rogue. Edit permissions through the manager rather than hand-editing admins.json, and never commit that file to a public repository.

Cfx.re-linked login versus local accounts

Linking an admin to their Cfx.re (forum) account moves authentication onto Cfx.re’s infrastructure, including its own 2FA, instead of a local password hash stored on your box. For most teams that is the safer default. Reserve local accounts for break-glass access, give them strong passwords and 2FA, and remove any admin promptly when someone leaves the team.

Protect the setup link, recovery PIN, and deployer

When txAdmin first starts it prints a one-time setup link and a recovery PIN to the console. Anyone who sees that console output during the window it is valid can claim the master account. Treat your console log and any pastebin of it as a secret, complete setup immediately, and never share startup logs publicly. The CLI recovery PIN should be used and then left to expire, not screenshotted into a Discord channel.

The deployer and recipes deserve the same caution. A recipe can run arbitrary setup steps, download resources, and execute commands during deployment. Only run recipes from sources you trust and have read, because “deploy this build” means “run this code on my server.”

Updates, backups, and audit logs

Keep txAdmin and your FXServer artifacts on a current, supported build. Security fixes ship in updates, and running an old artifact leaves known issues open. Before you grant a new admin access or run a deployment, back up your server data and database so you can roll back. Finally, use txAdmin’s action and audit logs: they record who ran what, when, and from where. Review them after granting access and any time behavior looks off, so a compromise is something you detect rather than discover.

Build on a secure foundation

Hardening the panel is most effective when the rest of your stack is solid. Run audited, well-built resources from a trusted source such as https://scripts-tebex.io rather than random leaked paid scripts, since a malicious resource can undermine every control above. Keep an eye on server performance and health with tooling like https://0resmon-tebex.io so an attack or runaway resource shows up as an anomaly you can act on. And for broader configuration and day-to-day server management, https://official-tebex.io covers the operational side that sits alongside your security work.

txAdmin security comes down to a few disciplined habits: keep the panel off the open internet, require 2FA on every account, grant the least privilege each admin needs, guard your setup link and recovery PIN, vet anything the deployer runs, and stay updated with backups and logs in place. None of it is exotic, and together it turns the most dangerous component on your server into one of the best-protected.
