Valheim
Crossplay, join codes, passwords and worlds.
Crossplay decides how people join
This is the one thing worth understanding before you invite anybody.
| Crossplay ON | Crossplay OFF | |
|---|---|---|
| How to join | 6-digit code | address and port |
| Xbox and Game Pass players | yes | no |
| Appears in Steam browser | no | yes |
| Code changes on restart | yes | — |
Your server page shows whichever one applies, so you can always copy the right thing. Change it in the Settings tab.
Your password
Valheim requires a password and we generate a strong one for you. It is on your server page with a copy button.
It cannot be part of your server name, and it must be at least five characters — Valheim refuses to start otherwise, which is why we do not let you set a weak one.
First start
Valheim generates its world before opening to the network, which takes a couple of minutes on a new server. Until it finishes, nothing can connect. This is normal.
Bringing an existing world
Upload both files — the .db and the .fwl — into:
.config/unity3d/IronGate/Valheim/worlds_local/Stop the server first, then restart when the upload finishes. The world name must match the server's configured world.
Still stuck? Get in touch with your server name and the last few lines of your console.
