Scopes

String|String[] Scopes define the access list the app needs. It can either be a string or an array of strings. Default scopes and always present are the mandatory from OpenID 2.0:

• openid
• email
• profile

OAuth2Client

OAuth2Client An instance of OAuth2Client is supplied for further use, mainly because this module no longer relies on googleapis nor it has as dependecy.
