Pairing

Pairing is authorization, not an account login. Pairfob has no username, email, or cloud account. Until it completes, the device cannot operate. After the computer confirms, this device holds a credential.

The credential stays in this browser on this device. Another browser, cleared site data, removing the PWA, or a private window means pairing again.

Opening pairing on the computer

On the computer that already runs pairfob:

pairfob pair

It will:

1. Prefer a QR code
2. Also print a manual code
3. Wait for the other device to prove the pairing secret
4. Ask for one Enter

There is no web confirm page. Do not look for an “Accept pairing” button in another machine’s browser — accept happens in this computer’s terminal.

Only one pairing at a time

If another computer also runs pairfob pair, the old code dies. The phone may say another computer started pairing, or that the code expired. Use the code this computer just printed.

Connecting the other device

Open pairfob.com/pair. The pairing page follows the same language as Pairfob (Connect your computer in English). A device that is already paired goes straight to the session list.

Scan (preferred) — Scan to connect

Point the camera at the QR on the computer. Camera permission is only for that scan.

Type it — Type the pairing code

Typing needs 8 secret glyphs + 6 locator glyphs. There is no 8-glyph-only hand entry.

• One field; paste all 14 glyphs (spaces and hyphens allowed; O → 0, I/L → 1)
• Eight glyphs only: the page asks for the rest and does not send

The two parts are different jobs:

Part	Length	Job
Pairing code	8	Secret. Proves you saw the computer screen
Locator	6	Finds that computer. Not the same class of secret

Enter on the computer

Only Enter on the computer actually admits the device. After the phone scans it still waits. Neither side shows security words. That stops a screenshot of the QR from pairing without you.

If it is not your device, refuse on the computer (Ctrl-C or wait for expiry) and run pairfob pair again.

Expired or wrong codes

A code is spent when used, and it also expires. Do not use a code from chat or last week’s screenshot.

Match the string on screen (English Pairfob):

You see	Meaning	Do this
That pairing code is spent or expired	Slot rotated, or the code is dead	Use the code the computer is printing now
Enter the full pairing code / 14 glyphs needed	Locator missing	Paste 8+6 together
That pairing code is incorrect	Does not match	New code; do not permute the old one
Pairing timed out	Network, or the computer left the wait	Scan or type the current code again
Too many attempts	This side is rate-limited	Wait
Another computer started pairing	A newer pair took the slot	Open pairing on the computer you mean to use

After pairing

• Opening pairfob.com/pair reconnects to the last computer this browser used
• Another computer on this phone: install pairfob there with the same command, run pairfob pair, then Settings → Switch computer → Add a computer — Multiple devices
• Another device: run pairfob pair again and scan with the new device — Multiple devices
• On the phone, Settings → computer card → Paired devices can unpair other devices. The computer can also pairfob forget N

Do not

• Paste pairing codes into someone else’s page or a group chat
• Clone a paired browser profile onto another phone
• Assume pairing finished before the computer confirmed
• Keep using an old code while two computers have pairing open
