{
  "error": "unsupported_grant_type",
  "error_description": "Invalid grant_type: password"
}  

this is the response from google authorization api , its not supported only authporization code is supported

Steps:

1. https://console.developers.google.com/ Goto url and create an API. (by clicking credentials>create credentials)

2. https://console.developers.google.com/apis/api/drive.googleapis.com/overview Goto url, click credentials> create new 0auth0.2 ( select applicaiton type as Web application)

3. While creating 0auth0.2 scroll down and set Authorized redirect URIs as https://localhost

4. CLick the download as json and then save the auth

6. Generate new token by filling the content as per the downloaded json ( open the json and fill postman as in json)
