Why is OAuth2 required?
The OAuth 2.0 authorization framework enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own …
How do I use OAuth2 authentication?
Authenticate using OAuth 2.0

Where is OAuth2 used?
OAuth is an authorization method to provide access to resources over the HTTP protocol. It can be used for authorization of various applications or manual user access.
How safe is OAuth2?
OAuth itself is very secure. However, as with any security implementation, it is only as strong as the weakest component. For implicit grant flow, such as your single page web application, the authentication occurs between the user and the Identity provider.
What’s the difference between OAuth 1.0 and 2.0?
OAuth 2.0 is the industry-standard protocol for authorization. OAuth 2.0 supersedes the work done on the original OAuth protocol created in 2006. OAuth 2.0 focuses on client developer simplicity while providing specific authorization flows for web applications, desktop applications, mobile phones, and living room devices.
Loosely speaking, if you plan to build a platform where third-party applications and services can access its resources, go with the authorization code flow; on the other hand, you can use the resource owner password credentials flow to build a client (a web/mobile application) for your own service. Tokens play an important part in OAuth 2.0.
Which is the latest version of OAuth protocol?
As an authorization framework enabling applications to access resources from all kinds of services, it is widely used on the web. Currently OAuth has two versions of protocols, OAuth 1.0 ( RFC 5849) and OAuth 2.0 ( RFC 6749 ).
