ValheimGuideManage Valheim admins, allowed players, and bans as dashboard lists, no adminlist.txt editing, plus the in-game admin commands and the 1.0 achievements warning.
Valheim normally makes you edit adminlist.txt on the server by hand. On Haptic, admins, allowed players, and bans are lists in your server's Admins section: add a player's ID, restart, done. The lists sync both ways with the actual files on the server, so nothing you set gets lost, and nothing set on the server is hidden from the dashboard.
Valheim identifies Steam players by their SteamID64, a 17-digit number. A player can find their own on steamid.io by pasting their Steam profile link. On crossplay servers, console and Game Pass players have a platform ID instead, shown in the same style.
Open your server's Admins section, add the player's ID to the admins list, and save. Changes are applied to the server on its next restart.
Adding IDs to the allowed players list turns your server invite-only: only listed players can join, even with the password. Leave the list empty and the password alone decides who gets in.
Add their ID to the banned list and save. Bans also apply from in-game with the ban command if you are an admin.
The lists survive everything. Your dashboard lists and the server's adminlist.txt, permittedlist.txt, and bannedlist.txt are kept in sync in both directions, including after restores and file edits. Editing either side is fine; nothing is silently overwritten.
Once your ID is on the admins list and the server has restarted:
Join the server and press F5 to open the console.
Admin commands work from there: kick <name>, ban <name>, unban <name>, banned to list bans.
Deeper commands (teleporting, spawning items, changing world modifiers) require typing devcommands first to unlock developer commands.
Achievement warning for Valheim 1.0. From the 1.0 release on September 9, 2026, Valheim has achievements, and Iron Gate has said that using most developer console commands permanently marks both your character and the world as modified, locking achievements for them. Everyday moderation like kick and ban is normal admin work, but think twice before devcommands on a world where achievements matter. Managing settings from your Haptic dashboard does not touch achievements.
