Chromium has done that to me before when I didn’t setup its keyring properly. I would just hit ESC three times to get past its dialog. Now I make sure to use an empty password for its keyring because I only use Chomium when something doesn’t work in Firefox.

KDE Plasma has also asked me many times for opening its keyring and that has pissed me off. I don’t use KDE Plasma other than on one server though.

Some of the other password requests you can disable in the graphical system settings (like asking for password coming out of suspend).

For the rest, those are just the same as Windows UAC which asks whether you want to give something adminstrator privileges. There’s probably a way to set up that experience if you’d rather click ‘yes’ in a popup than type your password.

EDIT: I suppose your comment is written in a way that it’s not clear whether you’re saying certain frequencies absolutely require meshes of a certain size to be blocked or if you’re just adding that extra detail about the design of Faraday cages for the hell of it. But…

Original comment: It doesn’t have to have holes to block radiation. A continuous sheet blocks all frequencies. A mesh is just nice so we can see through the cage or allow air to pass etc.

From the page you linked: “A Faraday shield may be formed by a continuous covering of conductive material.” “… if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation.”
