For anyone to have access to your Array lock, they will need to physically pair their device to the Array. This entails having physical access to the Array keypad, receiving an E-key invitation from your Array account and entering the encryption code, provided by the app, into the Array lock.
Even as an owner, you will not be able to log into another device with the same Array credentials and have immediate access to the Array. Any new device that will need access to the Array, will have to be paired to the lock.
