# Pairing a Head Mounted Device
> Select the Pair Device option from the User Menu on any screen-based device where you are already logged in, like mobile or desktop PC. We are showing an example from Altoura's phone interface.
Upon clicking Pair Device, the user will be redirected to a page that has 2 options to pair the device. They are
* a QR code
* a placeholder to add a pin-pairing code
Now, start the Altoura app on your Head Mounted Device - HMD (or any other secondary device) and choose the option "Pair Device".
On the HMD device if there is a scanner, like in the HoloLens, the QR code is scanned, and the pairing happens.
Also, in all HMD devices (HoloLens, Quest or VIVE) you will be given a six-digit code (PIN) to enter onto your first device.
Enter this PIN in the text box.
Your device is paired successfully.
