Yes, you can reset the sensor password from the manager.
Go to Devices > Global > Add and Remove Devices, select the sensor you want to reset the password for and select "Edit".
You will see an option for "Reset CLI Password". This will reset the password back to the default value of "admin123"
thx, but as I mentioned above "sensor is NOT connected to NSM", ok so probably there is no other chance how to reset password
Sorry, I should have read the question more carefully. I don't know any other ways to rest the password apart from using the manager or netboot.
