The process for finding a Bluetooth passkey varies depending on the device, with some featuring a dedicated code that appears in its product registration or instruction pamphlet and others automatically generating a passkey during the pairing process. Some programs or devices may also allow users to create a custom passkey or may not require one at all.
Bluetooth is a wireless transmission and communication technology that allows multiple devices or computers to connect with each other over a special connection. A Bluetooth passkey is a unique set of numbers that allows the operating system to ensure that it is connecting to the device in question. The process involves launching the Bluetooth manager on the computer or smartphone, initiating the device detection process, and choosing the appropriate device from the available list. Many computers automatically generate a unique passkey at this point, requiring the use to enter that same code on the device to complete the pair and allow access between the two devices.
Automatic code generation always displays the code on the screen of the device initiating the pair. If the device uses a static passkey, it may appear in its instruction manual or through a support website from the manufacturer. Depending on the nature of the device, the user may need to enter the code on the computer rather than the device, such as when pairing a wireless headset. Certain devices, such as mice, do not require a passkey to pair through Bluetooth.
