Receivers that are bundled with a Logitech product are paired with the device at the factory. When purchasing a replacement receiver or connecting multiple devices to one receiver, pairing requires the free-of-charge Logitech Unifying software, available for [[Microsoft Windows]] and [[Mac OS XmacOS]]. On Linux, the [https://pwr-solaar.github.io/Solaar/ Solaar software] can be used to adjust the configurations. Although not compatible with [[Bluetooth]], devices pair to Unifying Receivers in a similar way.<ref name=gallegos>{{cite web

Logitech receivers compatible with the Unifying protocol can be identified by the orange Unifying logo, which distinguishes them from Logitech Nano receivers of similar appearance, which pair in a similar mannersimilarly but only with a single device, without using the Unifying protocol.
 
Logitech Unifying Receivers (LURs) are often included in wireless Logitech keyboard, mouse, and combo sets, and may be purchased separately. Some Logitech peripherals allow a receiver to be stored inside.<ref>{{Cite web|url=https://www.logitech.com/images/pdf/userguides/multi_connect_instructions.pdf|title=Logitech Unifying Multi-Connect Utility Setup Instructions|website=Logitech}}</ref>

Each peripheral device can pair to one receiver per profile. While most peripherals only store one profile, newer products such as the Logitech MX Master, MX Anywhere series, and M720 Triathlon allow multiple profiles. These devices can be connected to multiple receivers simultaneously. This allows the use of receivers in several computers, e.g., a [[Desktop computer|desktop]] and a [[laptop]] [[computer]], selecting the computer to use by changing profiles on the mouse. This multi-computer function is further augmented by Logitech Flow (software KVM solution) which is similar to [[Synergy (software)|Synergy]]. For devices without multi-computer support, the receiver and input devices can be moved together from one computer to another, maintaining their paired status after being unplugged, as the pairing information is held in the little USB receiver<ref name="gallegos" />—this is much simpler than transferring the peripheral from one receiver to another by changing the setup in software, and also avoids the limitation to 45 pairings of older devices. This also allows the use of peripherals on computing devices that do not support Unifying Software, e.g. devices supporting [[USB OTG]] with operating systems such as [[Android (operating system)|Android]]: first pair to the receiver on a PC or Mac.<ref>{{cite web |url=https://community.musictribe.com/t5/Recording/Android-Tablets-and-Logitech-Unifying-Devices/td-p/236993 |title=Android Tablets and Logitech Unifying Devices|website=Music Tribe|date=7 January 2018|author=}}</ref>
 
Some older Unifying devices {{Specify|date=October 2024|reason=Which devices? How old?}} limit the number of allowable pairing changes to a maximum of 45 times. Once the 45th connection is made, it is no longer possible to connect such a device to a different receiver. For users who often switch a Unifying device between multiple PCs or laptops with individual receivers, this connection limit can become an issue. For example, a user who frequently switches a mouse between two receivers (e.g. at work and home) will quickly exhaust the limit of available pairing switches.<ref>{{cite web
