google auth2 info code example

Example 1: google oauth2 does token change when refresh

The Google Auth server issued Refresh tokens
never expire — that's the whole point of the
refresh tokens. The refresh token will
expire (or I should say become unauthorized) when the user
revokes access to your application.

Example 2: google gapi auth2 get current token

gapi.auth2.getAuthInstance().currentUser.get().wc.id_token
