At least for Duo, you can extract the HOTP secret [1] and use it in any OATH tool, e.g. with the otp extension of pass(1) on GNU/Linux (which uses uses oathtool(1) underneath). You can also do it a more difficult way, e.g. using the Duo app under anbox.

It's hard to break free of Android/iOS as well. I can almost guarantee that one or more apps, for example 2FA auth apps like Duo or Okta, wouldn't be usable on the GNU/Linux (I don't really know enough about them to be certain about this statement).
