Yes, the Password Store tools do this (actively delete the content from
the clipboard, after a configurable timeout).

Another common approach, similar to that, is to have a web browser
plug-in which reads the same database.

Thanks to WebExt support in both Chromium and Firefox, we have the
Browserpass <URL:https://dannyvankooten.com/chrome-extension-for-pass/>
extension that allows using credentials directly from a Password Store

I think you should move to the above model (tools like Password Store
that actively work to get the credentials out of the clipboard quickly)
as an immediate improvement first, and see how well that satisfies.
