Yes. People copy passwords, SSNs, crypto wallet secrets, and more in a clipboard that pretty much any app or website or system service can see without permission. I'm surprised we haven't seen more attacks on it, honestly.
I have long wanted to build a secure multi-clipboard, one where you can copy with Ctrl+shift+1, ctrl+shift+2 etc and paste with Ctrl+1 and Ctrl+2
It would keep those hidden from any app until explicitly pasted. I was thinking you could co-opt the system keyboard to get the same functionality, but it clears the system clipboard instantly after any copy/paste.
