Because some people don't get a static IP from their ISP and they don't want to go through e-mail verification every day. At this point, some sites require this workflow from me:

    1. Solve CAPTCHA for log-in form
    2. Log in with valid password
    3. Open E-Mail client, maybe even log-into your e-mail with the same workflow if not done yet
    4. Verify the IP via E-Mail 
    5. Surf to website log-in form again
    6. Solve CAPTCHA for log-in form again
    7. Log in again with a valid password
    8. Verify with 2FA code

Thanks, I hate it. It feels like step 1 to 7 could be skipped.
