Hi, We're working on an Azure Function that needs to authenticate against Azure AD. User interaction is not required. We've had some discussions around the best way to do this: Use the built-in App Service authentication and authorization support ( https://learn.microsoft.com/en-us/azure/app-service/overview-authentication-authorization ). Use Microsoft's OAuth 2.0 client credentials flow ( https://learn.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-client-creds-grant-flow ). We're looking at #2 as it seems easier to implement, however I'm not convinced it's necessarily the best way forward. Please advise the best way to authenticate against Azure AD in this scenario. Thank you

Hi, I would recommend taking this route. It's fairly simple and quite versatile. Please let me know if I can answer any questions! Best, James

Hi James,
Why would you recommend that route over another?

Thanks

Hi @kulmit bhambra , I recommend it because of a few reasons:

There's a lot of documentation to help you

It integrates easily with other areas of Azure AD

It's easy to troubleshoot any issues

It's easily configurable, and makes it simple to connect other platforms like Google if you need to in the future.

I hope this helps! If you're satisfied with the answer, please mark it as correct so it can help other users.

Thank you,
James
