How to Pair Your Logitech Keyboard and Mouse with Multiple Devices Using Logi Options+

Quick Answer

To pair your Logitech keyboard and mouse with multiple devices, install Logi Options+ on each computer, then use the Easy-Switch buttons to assign a channel per device. For cross-computer control, enable Logitech Flow in the software to move your cursor between screens and copy-paste seamlessly.

If you work across a laptop, desktop, and tablet, constantly unplugging and re-pairing peripherals wastes time. Logitech's Easy-Switch technology lets you connect up to three devices to one keyboard or mouse, and Logi Options+ makes the setup straightforward. This guide walks you through pairing, switching, and using Logitech Flow for a smoother multi-device workflow.

We'll focus on Logitech keyboards and mice that support Easy-Switch, such as the MX Keys S and M325S. You'll learn how to assign each device to a number key, troubleshoot common issues, and enable Flow for cross-device control. By the end, you'll switch between computers without touching a cable.

Why Use Logi Options+ for Multi-Device Pairing?

Logi Options+ is Logitech's configuration software that manages device settings, firmware updates, and multi-device features. It replaces older Options software and supports a wide range of recent peripherals. With it, you can customize buttons, adjust pointer speed, and enable Logitech Flow—a feature that lets one mouse and keyboard control multiple computers as if they were one desktop.

Without Logi Options+, you can still pair using Bluetooth or the USB receiver, but you lose advanced features like Flow and per-app customizations. The software is free and works on Windows and macOS. It's the essential tool for anyone juggling multiple devices, as it centralizes control and makes switching nearly effortless.

• Check that your Logitech device is listed as compatible in Logi Options+ before starting.
• Keep Logi Options+ updated to access the latest features and fixes.

Preparing Your Devices for Pairing

Before pairing, ensure each computer has Bluetooth enabled or a USB port for the Logitech receiver. If your keyboard or mouse came with a USB receiver, you can use it for one device and Bluetooth for the other two. Charge or install fresh batteries in your peripherals to avoid interruptions during setup.

Download and install Logi Options+ on every computer you want to connect. You'll need to pair each device individually, but the process is similar across systems. Note that some older devices may require the previous Logitech Options software, so check compatibility on the Logitech support page.

• Write down which Easy-Switch number (1, 2, or 3) you assign to each computer to avoid confusion.

Pairing Your Keyboard or Mouse with Easy-Switch

Easy-Switch is Logitech's technology that allows one peripheral to connect to up to three devices. On most keyboards, you'll find a row of number keys (1, 2, 3) that act as channel selectors. On mice, the Easy-Switch button is often on the bottom. Press and hold a channel for three seconds to enter pairing mode, then select the device in your computer's Bluetooth settings.

For example, with the MX Keys S for Mac, you can press the Easy-Switch key to cycle through devices. Once paired, you can switch instantly by tapping the corresponding number. The same principle applies to mice like the M325S, where a button on the bottom cycles channels. This method works without Logi Options+, but the software adds convenience by showing which device is active on screen.

• If pairing fails, move the device closer to the computer and try again.

Setting Up Logitech Flow for Seamless Control

Logitech Flow is a game-changer for multi-device users. It lets you move your mouse cursor to the edge of one screen and have it appear on the next computer, as if they were one display. Your keyboard follows the mouse, so you type on the same device where the cursor lands. You can even copy and paste files between computers, provided they're on the same network.

To enable Flow, open Logi Options+ on both computers, go to the Flow section, and follow the prompts. You'll need to pair both devices to each computer and ensure they're on the same Wi-Fi network. Once set up, you can drag windows across screens and share clipboard content. This feature is perfect for professionals who need to reference information on one machine while working on another.

• Flow requires both computers to be on the same network; a wired Ethernet connection can improve reliability.

Common Mistakes and How to Avoid Them

One common mistake is forgetting to assign a unique Easy-Switch channel per device. If two computers use the same channel, pressing that number will toggle unpredictably. Always assign each computer a distinct number and label them if necessary.

Another issue is outdated firmware. Logi Options+ often prompts for updates, but if you ignore them, features like Flow may stop working. Regularly check for updates in the software. Also, ensure that your Bluetooth drivers are up to date on your computers, as older drivers can cause connection drops.

• If Flow doesn't work, disable and re-enable it in Logi Options+ on both computers.

Step-by-Step: Pair Your Logitech Keyboard and Mouse with Multiple Devices

1. Install Logi Options+ on each computer: Download Logi Options+ from the Logitech website and install it on every computer you plan to connect. This software is the control center for pairing, customizing, and enabling Flow. Check that your device is compatible with Logi Options+; if not, use the older Logitech Options software.
2. Pair your keyboard and mouse to the first computer: Using the Easy-Switch channel 1, put your keyboard or mouse into pairing mode by holding the Easy-Switch key for three seconds. Then, go to Bluetooth settings on your computer and select the device. Make sure the device is fully charged or has fresh batteries to avoid pairing failures.
3. Assign channel 2 to the second computer: Press the Easy-Switch button to channel 2, then repeat the pairing process on your second computer. Each computer should have its own channel number to prevent conflicts. Label each channel (e.g., 'Work' and 'Home') in Logi Options+ for easy identification.
4. Enable Logitech Flow in Logi Options+: Open Logi Options+ on both computers, navigate to the Flow tab, and follow the setup wizard. Ensure both computers are on the same network and that Flow is enabled on both. If Flow doesn't work, verify that both computers are on the same Wi-Fi network and that the firewall isn't blocking the connection.
5. Test switching between devices: Use the Easy-Switch buttons to manually switch between computers, and then try moving your mouse to the edge of the screen to see if Flow takes over. Copy and paste text or files to confirm the connection. If switching is laggy, check for Bluetooth interference or move the receiver closer to the devices.
