Q: Does the keyboard lock in the open position so that you can use it on your lap?
A: It locks magnetically in the open position, but the magnets are not strong enough to securely keep the keyboard open when typing on your lap.

Q: Does the keyboard require an authentication code during pairing?
A: No. You are not required to enter an authentication code during pairing. Instead, once a phone, tablet, or computer has connected to the keyboard and automatically paired with it in Windows, Android, or iOS, the keyboard won’t connect to any other systems until you tell it to forget the current pairing. This is accomplished by pressing the Fn-Bluetooth key, which is the only way to put the keyboard in discoverable mode and make it visible to other devices that are in range. You can always tell when the keyboard is in this mode, because the blue light at the left-center will flash. This causes the keyboard to forget its prior pairing and be available for others to connect.
