The app proves that its protected device key belongs to the device receiving the licence.

    Choose “Activate this device”

    The app creates a protected P-256 device key. The private part never needs to leave the computer or tablet.

    Sign in as the purchasing adult

    Use the same email address used for payment and choose an available device seat.

    Finish activation and go offline

    The licensing service checks proof of the device key and returns a signed licence. Lessons then work without internet.
