# How to Connect to Your Satisfactory Server (/docs/satisfactory/join-server)



import { Step, Steps } from 'fumadocs-ui/components/steps';

> ⚠️ **Do NOT use "Join Game"** — this causes authentication errors. Use **Server Manager** instead.

5. Enter the player password if set
6. Click **Connect/Join**
