Vender cannot push updates now that 2FA is on.

My vender (buildfire) cannot push updates due to 2FA being turned on. With 2FA now being mandatory I cannot turn it off. So I have to setup a confernce call with vender to give them code that 2FA sends to my phone via text so they can log in. I update the app with new content 2-3 times a week, so that many confernces calls weekly is not practicle. Is there a way around this?
