MFA is problematic for development of a 3rd party integration

We have a developer account used for development of an integration to Constant Contact.  The problem is with the MFA suddenly being required to be set up when I logged in the account, I would have to tie the MFA to a specific person and phone number and a mobile app.  This is not practical for a development environment where multiple developers need to use the same application account (API Key, etc) for developing our integration.    We need to be able to create a true developer account that is not tied to a specific phone number or email but supports multiple users for a programatic integration.
