2FA Setup
No luck. I'm on first page of Apple ID with my name and personal symbol. I must still be signed in because I see no password box. Selecting difference pane on left doesn't help, nor go to iCloud. Am I on correct page?
You need another trusted device or telephone number.
See Two-factor authentication for Apple ID - Apple Support:
A trusted device is an iPhone, iPad, or iPod touch with iOS 9 and later, or a Mac with OS X El Capitan and later that you've already signed in to using two-factor authentication.
All settings for the Mac are in System Preferences. The particular one related to this topic would be Apple ID in Catalina or iCloud in earlier versions of macOS.
Verification codes cannot be received if the device is offline. Usually, iDevices are always online but computers are not always online. Nevertheless, verification codes will only be sent to your trusted devices. Here are more links of trusted devices, since I do not know if you've read them:
