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.

Hello RobertH4988,


Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.


If your inquiry is related to multiple developers needing direct access to the app's details after registration, we’d probably want a little more information regarding what specifically they need access to (are they needing to edit / register additional redirect URIs, re-generate the app secret, etc.) and also what the use case is for that necessity so that we know what you are wanting to do and can potentially provide better insight or possible resolutions.


If they just need to be able to access the UI for testing purposes, one option may be to create multiple users so that each of your developers is able to log into the UI. The number of users you're able to add to your account depends on the type of email plan you have. Trials offer upto 3 account users, the Email plan offers 5 account users, and Email Plus offers an unlimited number of account users.

Additionally, MFA has Voice Call authentication available if your organization is located within an office that has a main line which employees can access:
