The OAuth and OIDC specs (and extensions) cover authentication and authorization for: Users logging into a server-side web application. Users logging into a client-side web application.

What is OAuth used for?

OAuth is a delegated authorization framework for REST/APIs. It enables apps to obtain limited access (scopes) to a user’s data without giving away a user’s password. It decouples authentication from authorization and supports multiple use cases addressing different device capabilities.

Does Google use OAuth?

Google APIs use the OAuth 2.0 protocol for authentication and authorization. Google supports common OAuth 2.0 scenarios such as those for web server, client-side, installed, and limited-input device applications. To begin, obtain OAuth 2.0 client credentials from the Google API Console.

What is difference between OAuth and OAuth2?

Why do we use OAuth2?

If not then most likely, you don’t need to implement OAuth. But if your data is sensitive, such as private user data, then you need to put some sort of security layer on your API. Also, using OAuth or other token based security can help you build a better permission checking across your user base.

Who created OAuth?

OAuth started around November 2006, while Blaine Cook was working on the Twitter OpenID implementation. He got in touch with Chris Messina looking for a way to use OpenID together with the Twitter API to delegate authentication.

Why OAuth is bad for authentication?
