I recently created a secondary Google account and wish to enable Two Factor Authentication using standard HOTP, such as Google Authenticator.
However when I go to my account's security settings, 2-Step Verification, I get this:

I only see options to verify through sms or phone call, or a physical security key, or a Google Prompt on my phone. Neither of these is what I need.
Note that in this case there is actually no phone involved whatsoever. I only created this account on my laptop. I'm using HOTP 2-FA on my main Google account so I know it's possible, but I can't seem to enable it here on this new account?
Am I looking in the wrong place? How or where can I enable regular 2-FA, not involving a phone or hardware key?
(P.S. note that I mention 'Google Authenticator' because that's the most commonly known implementation of HOTP 2-FA and probably how Google will refer to it, I will actually be using either Aegis or KeePassXC)
