Client ID/Certificate
The Client ID/Certificate credential type authenticates with SharePoint Online using certificate-based authentication. Use this credential type when configuring SharePoint Online source groups.
This requires a registered application in your Entra ID tenant. The certificate itself is generated by the source group wizard — you don't create or upload it here.

Certificate
The certificate is not entered in the service account form. When you set up a SharePoint Online source group, the wizard includes a Generate and Download Certificate step that creates the certificate and downloads it to your machine. You then upload the certificate to your registered Entra ID application in the Azure portal before testing the connection.
If you update the service account on an existing source group, the new account's certificate must be uploaded to the registered app before saving.
For steps to register the application and upload the certificate, see SharePoint Online Connector Requirements.
