After watching the video you will understand:

• OAuth2:
• The Authorization mechanism
• Better than Client Login:
• OAuth2 is more secure
• More specific access control
• No CAPTCHA challenges
• Using OAuth2:
• Registering your application
• Making the authentication requests
• Where OAuth2 tokens fit into regular service calls
• Implementing OAuth2:
• Full support in our client libraries
• What refresh and access tokens are
• Authorization Flows:
• Installed Applications Flow
• Web Server Flow
• Best Practices:
• Storing refresh_tokens

With that knowledge, updating your applications to use OAuth2 should be trivial. All the client libraries have comprehensive support for OAuth2 and helpful examples to demonstrate its use. For further information on configuring OAuth2 in any of the libraries, see the table below.
