TOTP tokens on my wrist with the smartest dumb watch
Is there some Unix-ish tool to generate these TOTPs on a laptop? I don't like to keep the 2nd factor on a small mobile device that is easy to lose. So I ask about a laptop tool.<p>By Unix-ish I mean something that is small and does one thing well. Like pipe in a secret to it and it gives me a TOTP? Pipe in multiple secrets and it gives me multiple TOTPs? Then I don't have to remain beholden to a custom encryption format. I can encrypt my secrets with other Unix-ish tools, decrypt it, pipe it to this tool and get my TOTPs. Recommendations?
