Brightcove's implementation of OAuth2 allows you to get access tokens for various Brightcove APIs.
Brightcove's implementation consists of two parts:
The OAuth API - provides access to all available OAuth functionality.
The OAuth Credentials UI - accessible through the Account Settings interface in Studio, the UI provides an easy way to register apps that will use Brightcove APIs and generate a client ID and client secret for them. See Managing API Authentication Credentials for instructions on using the OAuth UI.
