My Android device (v. 7.1.2) offers several options to use the "Smart Lock" feature.

This feature uses some rules to automatically disable the lockscreen.

Available rules are:

• Trusted place
• Trusted Bluetooth device
• Trusted face
• Trusted voice
• On-body detection

I am surprised that there is no option to use a trusted WiFi network.

Some forums state the risk for the WiFi network to be spoofed. I don't understand how the risk is different: an attacker could spoof a Bluetooth device as well.

What could be reasons for not allowing a WiFi-based unlocking while allowing Bluetooth-based unlocking?
