Server authentication problems

Reviewed October 26, 2026 1 min read

A Hytale server in authenticated mode has to be linked to a Hytale account with /auth login device. Most problems come down to a few cases.

The code stopped working
Device codes expire after 900 seconds (15 minutes). Run /auth login device again and use the new code right away at accounts.hytale.com/device.
How do I know it worked?
The console shows «Authentication successful! Mode: OAUTH_DEVICE».
Players can't join and the console mentions authentication
The server isn't linked yet, or the link was lost. Repeat the login.
Is there a limit?
According to the official manual, each Hytale license can authenticate up to 500 servers.
Worth knowing

Don't switch to offline mode to skip this: in offline mode the server doesn't verify players' accounts.
