If you need a secure login system for your Chrome Extension, but you don’t want to or don’t know how to create all of the necessary gear–authentication servers, databases…—you can use the oAuth2/OpenID Connect protocols (specifically OpenID Connect) to create one for you.

By delegating the authentication (different from authorization) of your login system to a secure, trusted login system like Google’s, you can have a safe and secure system for your Chrome Extension up and running in no time.

We’ll first “register” our extension to get a unique key, then we’ll head on over to the Google Developer’s console to get ourselves an OAuth2 Client ID.

Finally, I’ll show you how to construct the OAuth2 Endpoint URL, and use it with the Google Identity API.
