2 Factor Authentification for sites in Linux program

Github demands that I use 2 Factor Authentication. Github proposes to use one of these: - https://support.1password.com/one-time-passwords/ - https://authy.com/guides/github/ - https://www.microsoft.com/en-us/security/mobile-authenticator-app I would like to not use my phone, but a program on my Kubuntu. Basically, I would like to screenshot, instead of using my phone. Is this possible and with what program?
