Good, speaking of security i would advice you to try Ravio OTP instead of Authy but the problem is no support Windows so only iPhone & Mac. im worrying about it i am trying to find good like Ravio, Authy is not very security ;/
The KeyChain is complicated and mess up sometimes because of iCloud software for Windows i dont like it and not sure about the security, i would say use Bitwarden which it would be easy for you to use Windows as PC since an iPhone isn't nearly you sometimes, and you dont have Mac right obviously
