Hi
@ste92
When you say 'Access Password' do you mean to the camera itself or to the Hik-Connect account?
If you don't know the camera password you will need to reset that first using SADP - see this
How-To Guide - or hard reset the camera using the reset button on the back of the camera and set your own password.
If you do know the password or have just reset it then you can disconnect the camera from the Hik-Connect account by using
Unbind in SADP.
