Additional Information
OBDassistant supports two ways for OAuth 2.0. In one way, Google opens a page in your browser. It gives you a long-lasting access token. In the other way, you need two pages: one for getting permission and one for exchanging tokens. The refresh token gets a new access token when the old one expires. This makes the sign-in process smooth and safe for users.
