Would like to now how I can I setup whatsapp to work with my facebook account, and my instagram account

HI I would like to get some help please. I would like to be able to setup whatsapps messenger with my personal facebook account. I do not have a business account so I am not using whatsapp for business. The reason I want to setup whatsapp with my free facebook account is because I am getting tired of going to an email address to get a code to get into my two step verification or 2fa. I do not have my facebook account or my instagam account linked at all. I want want to link one account at a time with whatsapp. could you please provide some screenshots on how to setup whatsapp with my facebook account please. I like screenshots much better to see. I find small print hard to see.
Do I have to use whapps web in order to receive codes for my facebook account or do I have to have the whatsapp application on my desktop to receive account codes or does it matter. Please feel free to describe the full procedure on wether I need to do anything special in my facebook and my instagram account to setup whatsap for these accounts.
please feel free to put this question in a different area or discussion on this forum I just was not sure where to put this question.

Thanksp

I really don’t use any of those platforms so I can’t help much with anything relating to Meta. But assuming you’re on a desktop, you can usually use ctrl+ to zoom in and make small print in a browser larger.

HI I would just like to add that I use my email address to login to facebook but I would like to get rid of my email address so I just receive codes through whatsapp and get no more security codes through my email address their any way to delete my email address from my facebook account. Thanks.
