Will I need to set up the Multi-Factor Authentication (MFA) for my Salesforce integration account to authorize Heroku Connect to have access to the data?

Issue

Salesforce will begin to require all users who log into Salesforce products to use Multi-Factor Authentication (MFA) on February 1, 2022. Will MFA be required to log into Salesforce and complete the Heroku Connect configuration?

Resolution

Yes, the integration user must log into Salesforce with MFA to complete the setup while MFA won't affect existing connections. Please also check this article, Will I need to reauthorize Heroku Connect after enabling MFA for Salesforce, for more details.
