Published 2026-10-20, updated 2026-10-20, by ZeroXR, the maker of Model Explorer (https://0xr.space/).

On your phone, open 0xr.space/headset and sign in with the 6-digit code from your email. The phone shows a large code. On the Quest 3 or 3S, press Scan and look at it, press Sign in when the headset asks Sign in as you on this device, then press Allow on the phone. There is no typing on the headset.

A code lives two minutes and works once; while the page stays open, the phone shows a new one before the old one runs out. Allow is always asked, whatever network the headset is on. If two devices scan the same code it ends, and the phone says This code was scanned by two devices. Show a new one. A headset signed in this way lasts no longer than the phone's session. Quest 2, Quest Pro and Pico have no camera a page can use, so they sign in by email.

## Steps

1. On the phone, open 0xr.space/headset, sign in and keep the code on screen.
2. On the headset, open 0xr.space or the Model Explorer app and press Scan on Home.
3. Look at the code, then press Sign in when the headset asks.
4. Press Allow on the phone. The headset shows Signed in as your address.

## Questions

### The headset says Waiting for Allow on your other device.

Press Allow on the phone that shows the code. Nothing signs in until you do.

### It says That sign-in code has expired.

Codes last two minutes. Press Show a new code on the phone if a new one did not appear, and scan again.

### I am already signed in on my phone. Where is the code?

Open Settings, press the row with your address, then Sign in on a headset.

### The wrong headset signed in. Can I undo it?

Yes. Press Not your headset? Sign it out on the phone, or sign it out under Devices in Account.

### It says This device is signed in to another account.

A scanned code never switches accounts. Sign out in Account on the headset first, then scan again.
