OAuth (Angular)

The OAuth2 component provides a simple way to authenticate users so they can gain access to your cloud data sources.

When users sign-in using OAuth2, your application gets an accessToken that identifies the user, which may provide them with permissions to read and write to the data source.

This example uses Angular.
