How to disable Google Ads two-step authentication

I currently am using my Gmail for SMTP for my site. But I also signed up for Google Ads. To sign into Google Ads, I have to two-step authenticate. But because of this, it disables the SMTP for my website.

I would like to keep my SMTP as is. How do I disable the two-step authentication? I am familiar with toggling it on and off by going to but that means one will always be disabled.
