How does QR code IPTV device pairing work? The TV creates a short-lived pairing session and shows a code or QR. A signed-in user on the web claims that session. The TV then redeems a one-time login token using a device secret. Proper designs hash codes at rest, require the device secret to fetch tokens, rate-limit guesses, and mark tokens single-use to prevent session hijacking.
Why not type passwords on the TV?
Remote keyboards increase typos and shoulder-surfing risk. Pairing keeps secrets on the admin surface (web) and delivers only a session to the living room device.
