Is mandatory multifactor authentication (MFA) for my tenant, effective October 15, 2024, going to affect the authentication and API calls through the App Registration created using Microsoft Entra ID?
Will existing API calls fail if MFA is set up for the tenant?
Currently, the client credentials flow is being used to authorize API calls.
Despite reviewing the guide that accompanied the email, there seems to be no information addressing this concern.
Thank you.

@Warren Baguis Just checking in to see if below information was helpful. If you have any further updates on this issue, please feel free to post back.
No, if you are using the client credentials flow there will be no impact. The changes Microsoft is introducing are specific to user logins and only affect the resources listed in this article: https://learn.microsoft.com/en-us/entra/identity/authentication/concept-mandatory-multifactor-authentication
