   @swamy16 : @darylerwin is correct. To use default credentials you must set the `GOOGLE_APPLICATION_CREDENTIALS` environment variable.
   
   As an alternative, I've filed https://github.com/mxmzdlv/pybigquery/issues/14 to allow specifying path to service account key file via the connection string.
   
   **Linux or macOS**
   
   Replace [PATH] with the file path of the JSON file that contains your service account key.
   
   ```
   export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
   ```
   
   For example:
   
   ```
   export GOOGLE_APPLICATION_CREDENTIALS="/home/user/Downloads/service-account-file.json"
   ```
   
   **Windows**
   
   Replace [PATH] with the file path of the JSON file that contains your service account key, and [FILE_NAME] with the filename.
   
   With PowerShell:
   
   ```
   $env:GOOGLE_APPLICATION_CREDENTIALS="[PATH]"
   ```
   
   For example:
   
   ```
   $env:GOOGLE_APPLICATION_CREDENTIALS="C:\Users\username\Downloads\[FILE_NAME].json"
   ```
   
   With command prompt:
   
   ```
   set GOOGLE_APPLICATION_CREDENTIALS=[PATH]
   ```
