I think implementing a TOTP (or other OTP mechanism) would be a great tidbit of added security. In the day and age of password managers, passwords often pass thru our clipboards. In some cases, if Clipboard Fusion is syncing to the cloud, then secured data is permanently or semi-permanently etched into another system thereby making it a critical system to be protected at all costs.

Additionally, I believe OTP authenticators to be much more secure. Products like iMessage and remote Android apps which disperse messages and notifications to external devices/systems mean the code isn't only in one place but can end up in many locations.
