Single Sign-On Clarification

If we enable single sign-on, is it possible to prohibit users from logging into the platform using their username and password once SSO is in place? (Disable login via username and password in favour of SSO.)


Ideally, for ALL users. (Even the user which initially created the account.)


I am not very familiar with SSO, so perhaps the answer is clear enough from the documentation, but it wasn't obvious to me. (Based on my limited knowledge of SSO.)

Hello Osman,


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.


Currently, SSO implementation is only available for Constant Contact Partners. When it is enabled, Only the Account Owner user role logs in via SSO. Other user roles on an account such as the Account Manager and Campaign Creator Roles would login via Constant Contact username and password. Below I’m including our current V3 API documentation on Partner SSO.

Ah. I see. That's unfortunate. Our understanding (misunderstanding) was that SSO was available for all accounts. And a “Constant Contact Partner” is a company involved in developing integrations with Constant Contact? Correct?


If so, is there anything on the horizon that will allow companies to use SSO for login in the near future?


Thank you for the quick reply here. Very much appreciated.
