I would avoid Authy's desktop app. It's a 144MB app (due to Electron) to show OTP keys. Kind of ridiculous... For standard OTP, I use 1Password. It integrates well, syncs with my devices, and is still locked behind a secured central password (or fingerprint, in the case of my mobile device). It's secure enough for my needs while still being performant and encouraging of good habits, such as randomized, unique passwords.
