This is a most excellent place for technology news and articles.
That is true, though you could keep your password and totp databases separate theoretically. I'm not sure if keeping them in say separate apps brings much benefit if your phone/pc gets compromised though, as most people would have both available on their device... totp is more about convince, it's never as secure as a hardware thing say yubikey.
