API only user and multi-factor authentication

From February 1, 2022, Salesforce will require users—other than API only users—to have multi-factor authentication enabled. We recommend that you make the API user an API Only user and do not enable multi-factor authentication for that user. The API Only user will not be able to access the Salesforce user interface.

For information about this change in Salesforce, see Salesforce Multi-Factor Authentication FAQ (Salesforce help).
For information about how to create the API Only user in Salesforce, see Create a secure Salesforce API user (Salesforce help).
