Linux clipboards have been a pain point to me for decades. What I really want is a single unified clipboard daemon that works across different login sessions and covers console and graphical environments with the same keyboard shortcut. Bonus points if it's got a single-use-paste option for passwords, and also buffers to hold onto multiple selections.
This wouldn't prevent the malware that's constantly scanning the clipboard from stealing your password; it would only prevent you from using it after it's been stolen.
For clarity, are you expecting a clipboard in full terminal sessions (including serial?) or are you just meaning pty sessions with a terminal emulator?
I'm not sure how a clipboard manager would know the text copied in was a password (or 2fa).
