Google Home not asking for pin

I set up Google Assistant to connect with my local Home Assistant. It works as expected and I was able to expose covers and also set the PIN for security devices. But, whenever I try to open the covers, I actually just opens them without asking for the pin.

Any ideas?

Have the same problem, did you found a solution?

Unfortunately no solution yet. Don’t know what the reason is. Maybe its a bug in HA.
