ZERO (all caps) is the Bluetooth OBDdroid Dongle PIN

What's the PIN for pairing with our ZERO OBDdroid Dongle?

The Bluetooth Pairing PIN for any of our Zero OBDDroid products is ZERO (all caps).

Please know that we program and test each Dongle such that the PIN is deliberately not a 4-Number PIN. Alphanumeric PINS for all Bluetooth devices should be used to thwart hackers from getting to your Android device/files while using Bluetooth communications. Numerical Digits have only one state which makes it easy for attacks; keeping PINS at the default factory code is a very BAD idea for manufacturers to embrace, especially if PINS cannot be modified by the user, as is the case with many Bluetooth Devices.
