In the QRoll teacher console, open
⚙ Settings → Offline Quick Attendance and tap
Enable on this device. Copy the pairing code it shows and paste
it below. The code is shown once.
Pairing stores a token for this app only. It can read your class
lists and submit attendance — nothing else. It cannot open the console,
read marks or change settings, and you can revoke it from the console at
any time. Your 6-digit PIN is not stored here.
