To whitelist players on a FREAKHOSTING SCP: Secret Laboratory server, turn on Whitelist in Security and anti-cheat on Game settings (the enable_whitelist setting) and save. Then add each player’s SteamID64 with @steam, one per line, to UserIDWhitelist.txt in the same folder as config_gameplay.txt, and restart. Only listed players can join.

​
Before you start

  • Start the server once and accept the EULA, so the config folder exists.
  • Collect the SteamID64 (a 17-digit number starting with 7656) of every player, including yourself.

​
How to turn on the whitelist

1

Open Game settings

Click Game settings under GAME SETTINGS and find Security and anti-cheat. Type whitelist in Search settings to jump to it.
2

Turn on Whitelist

Switch on Whitelist (“Only players on the whitelist can join.”). Click Review and save and save.
3

Open the config folder

Click Files and open .config/SCP Secret Laboratory/config/<port>/, the folder for your server’s port.
4

Edit UserIDWhitelist.txt

Open UserIDWhitelist.txt. If it isn’t there, create a new file with that exact name. Add one player per line:
Lines starting with # are comments. Discord accounts use the Discord user ID with @discord.
5

Restart

Save the file and restart the server.

​
How to remove someone from the whitelist

Delete their line from UserIDWhitelist.txt, save and restart. To open the server to everyone again, switch Whitelist off on Game settings and save.

​
Frequently asked questions

​
Why can’t a whitelisted player join?

Check that the line has the full SteamID64 and ends with @steam, with no spaces. Check you edited the file in your port’s folder, and restart after saving.

​
Is a whitelist the same as a password?

No. config_gameplay.txt has no join password setting, so the whitelist is the way to keep an SCP:SL server private.

​
Can whitelisted players skip geoblocking?

Yes, by default. geoblocking_ignore_whitelisted is true in config_gameplay.txt.

​
Will my server still be on the server list?

Whitelisted servers can be listed when verified, and players can hide whitelisted games with a filter in the server browser. See not showing in the list.
