Someone who has stolen or found your phone would first need to know your phone’s passcode (if you have one) and then know that Klevio is an app for unlocking your doors. Then they’d still need to find out where you live.
You can set a pin on your Klevio app for added security. You can also log into Klevio using someone else’s phone and let yourself into your house.
In the meantime, your traditional keys will still work.
