Took me a bit to figure out how to use the 2FA with 1Password, but it is possible.
Every time I clicked the "2FA installation link" button, it would want to open System Setting on macOS.
The thing for me to do was:
- Copy the link
- Go to the account in 1Password
- Click Edit
- Click "+ add another field"
- Paste the link in the "one-time password" field
- Save
