WI-FI passwords do not hide

Is there any way in acs not to hide the wi-fi passwords? Because I took routers that are always showing the password and routers that any event of the cpe the password turns blank. Is this from manufacturer to manufacturer?

There are some models that don’t report back the Wi-Fi password. Sadly, in those cases there is nothing to do.

From the specification:

…When read, this parameter returns an empty string, regardless of the actual value.
