This guide explains how to enable and use SSH on your Steam Deck for remote access to its files. The Steam Deck's desktop mode allows for functionalities beyond gaming, making remote file access a valuable feature.

Enabling SSH on the Steam Deck

Follow these steps to enable SSH:

1. Power on your Steam Deck.
2. Access the Steam menu, navigate to Settings > System > System Settings, and enable Developer Mode.
3. Return to the Steam menu and select Power > Switch to Desktop Mode.
4. Open Konsole from the Start menu.
5. Set a password (if not already set) using the command: passwd.
6. Enable SSH using the command: sudo systemctl start sshd. To ensure SSH starts automatically after a reboot, use: sudo systemctl enable sshd.
7. You can now access your Steam Deck remotely using a third-party SSH client.

Caution: Avoid modifying or deleting system files to prevent OS corruption.

Disabling SSH on the Steam Deck

To disable SSH:

1. Open Konsole from the Start menu.
2. Use sudo systemctl disable sshd to prevent SSH from starting automatically on reboot, or sudo systemctl stop sshd to immediately stop the SSH service.

Connecting to the Steam Deck via SSH

After enabling SSH, use a third-party application like Warpinator for easy file transfer. Install Warpinator on both your Steam Deck and your PC, then launch it on both devices for seamless file sharing.

Alternatively, if using a Linux PC, you can directly connect via your file manager. Enter sftp://deck@steamdeck in the address bar and provide the password you set earlier.
