What does "keyless security" mean?

You can choose from one of the following keyless modes:

None: Bluetooth keyless entry is fully automatic.

This mode is the least secure keyless mode, as the access control system cannot tell whether the user is approaching the system or walking past it.

Touching the device :Bluetooth keyless entry is achieved by touching the device.

Smartphone action: Bluetooth keyless entry is achieved via a notification on the smartphone or tablet.

With access credential: Bluetooth keyless entry is achieved using a stored access credential on the device. The access credential may be a fingerprint, a PIN code or a transponder key.
