This is a most excellent place for technology news and articles.
Yup, most 2FA is just TOTP, which is a pretty simple, open standard and is hardware independent. All you need is a key (the QR code or the numbers) and access to a reliable time source and you can make a TOTP app on anything.
I use Aegis on my phone and Authenticator on Linux (some GTK app), and they both produce identical codes for the same key.
