I know this idea is a little ridiculous, but it just popped into my head: what about using one of those rubber ducky USB keys that pretend they're a keyboard and enter certain keystrokes? You could have it enter the password when inserted.

Or, perhaps a physical password manager that can store multiple passwords, with a labeled button for each?

I'll have to look into that -- it might work.
