# How to Add an Allowlist to your SCP: Secret Laboratory Server

Learn how to easily set up an allowlist on your SCP: Secret Laboratory server using Nodecraft. Protect your community and restrict access to authorized players.

In this guide we are going to cover how you can set up a whitelist on your SCP server. A whitelist is a great way to moderate your server and ensure that players that join your server are only ones that you have allowed to join.

## Adding a player to the whitelist

1. Open your dashboard
2. Locate your SCP server and click on the **panel **button.
3. Once you are on your SCP panel, stop your server then navigate to the **Game Settings **page.

4. Once on the settings page, click on the **Security **tab.

5. On the security tab ensure **Enable Allowlist/Whitelist** is turned on under the **Access Control** section then click submit.

6. Once the whitelist is enabled then navigate to your** File Manager**.

7. Once on the file manager, navigate to following folder:` /.config/SCP Secret Laboratory/config/<ServerPort Number(Typically 7777)>/` .

9. For the next part you will need your or the players SteamID64 which can be looked up on [SteamID.net](https://steamid.net).

10. Once on the website, enter the steam username you’d like to get the ID for and click **lookup**.
11. Once looked up, the Steam64ID will appear listed below.
12. Once you copy the SteamID64 go back to the file UserIDWhitelist.txt and paste in the ID on a new line being sure to add **@steam** after the steamID64.   
  ![The UserIDWhitelist.txt file open in the Nodecraft text editor, with a red box highlighting a line of code showing a player's SteamID64 correctly appended with @steam under a comment placeholder.](https://cms-a.nodecraft.com/f/133932/1026x243/413f99f1b6/scp-sl-whitelist-steamid64-format-example.png/m/)
13. Once you have added the players to the file, click **save**.   
  ![Close-up of the Nodecraft code editor toolbar showing a red box highlighting the green Save Changes button next to Rename, Copy, Move, and Delete options.](https://cms-a.nodecraft.com/f/133932/448x113/2a12ecf78e/nodecraft-file-manager-save-changes.png/m/)
14. Start your server.

## Conclusion

You have now enabled the whitelist on your SCP server. Your server will now only allow those you have been added to the whitelist to join your server.
