Tailscale Installation

Tailscale is a secure, easy-to-use VPN that allows devices to communicate with each other as if they were on the same private network.

This guide explains what Tailscale is, what it is used for, and how to install it on supported operating systems.

What is Tailscale?

Tailscale creates a private encrypted network between your devices using WireGuard.

Once installed and connected:

• Devices receive a private VPN IP address
• Devices can communicate securely
• No port forwarding is required
• No router configuration is required

Tailscale works automatically across different networks and locations.

What Tailscale is used for in Turn Off PC

In Turn Off PC, Tailscale is used to enable remote control features.

When devices are connected through Tailscale, Turn Off PC can:

• Shut down a computer remotely
• Put a computer to sleep remotely
• Restart a computer remotely

Without Tailscale, these features work only inside the local network.

Requirements

To use Tailscale, you need:

• An internet connection (for setup and coordination)
• A supported operating system
• A Tailscale account (free tier is sufficient)

IMPORTANT: Tailscale must be installed on BOTH devices:

• The computer you want to control (Windows/macOS/Linux)
• Your mobile device running Turn Off PC (Android/iOS)

Both devices must use the same VPN and be connected to the same Tailscale network.
