I think I might get cut off.

Is it not still the case that github's 2fa needs a program running on a
mobile phone, or an SMS-capable mobile phone? Is there any support for
normal tools running on a normal Linux machine?

(I think last time I tried to use the SMS route, it refused to send SMS
messages to my landline, despite the fact that I can receive them)
