Additional Context

If --auth mode login doesn’t work, then I shouldn’t get a warning message that says to use it!

Currently we only throw warning message for all possible credentials missing scenarios.

Outputting informational message to stderr is in violation of decades of expected behavior of stderr. Informational messages typically belong in stdout.

If you are not sure how to fix this or authentication is upstream provider out of your control: A wrapper function that will try/catch each auth method and only outputs to stderr if none of the authentication methods were successful could handle this for you.

--only-show-errors implies only showing errors, no informational output. I (and everyone else) can add this but it is a backwards workaround for a problem that shouldn’t exist. This flag really shouldn’t exist.

Hi @Juliehzl - This issue should probably be reopened as the problem that was mentioned has not been resolved (unless I’m missing an update). I only ended up finding this issue because of the mentioned error message - only to find out that --auth-mode login is not supported. Having an accurate error message would have saved this investigative time for myself and others.
