This module lets you authenticate using Google in your Node.js applications. By plugging into Passport, Google authentication can be easily and unobtrusively integrated into any application or framework that supports Connect-style middleware, including Express.
1Password, the only password manager you should trust. Industry-leading security and award winning design.
$ npm install passport-google-oauth20
Create an Application
passport-google-oauth20, you must register an application with
Google. If you have not already done so, a new project can be created in the
Google Developers Console.
Your application will be issued a client ID and client secret, which need to be
provided to the strategy. You will also need to configure a redirect URI which
matches the route in your application.
The Google authentication strategy authenticates users using a Google account
and OAuth 2.0 tokens. The client ID and secret obtained when creating an
application are supplied as options when creating the strategy. The strategy
also requires a
verify callback, which receives the access token and optional
refresh token, as well as
profile which contains the authenticated user's
Google profile. The
verify callback must call
cb providing a user to
var GoogleStrategy = Strategy;passport;
passport.authenticate(), specifying the
'google' strategy, to
For example, as route middleware in an Express application:
Developers using the popular Express web framework can refer to an example as a starting point for their own web applications. The example shows how to authenticate users using Facebook. However, because both Facebook and Google use OAuth 2.0, the code is similar. Simply replace references to Facebook with corresponding references to Google.
Passport is open source software. Ongoing development is made possible by generous contributions from individuals and corporations. To learn more about how you can help keep this project financially sustainable, please visit Jared Hanson's page on Patreon.
