Occasional Contributor

I have a C# Application that reads O365 groups and teams Information using graph API and generates a report. I am able to read and write teams info using graph API by authenticating using tenant info, client id and secret key (these values come from Azure APP registration). I am trying to avoid this App Registration step(tool requires client id and user login to get information). Is there any possible way to do authentication without client id?(like graph explorer does)


Above auth provider link doesn't have any authentication without clientid.

Authentication used in the tool:

static String[] sca = { "https://graph.microsoft.com/.default" };

var auth = PublicClientApplicationBuilder
InteractiveAuthenticationProvider authProvider = new InteractiveAuthenticationProvider(auth , sca);
