OAuth2 vs OAuth.io: What are the differences?
Developers describe OAuth2 as "An open standard for access delegation". It is an authorization framework that 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 behalf. On the other hand, OAuth.io is detailed as "OAuth That Just Works". OAuth is a protocol that aimed to provide a single secure recipe to manage authorizations. It is now used by almost every web application. However, 30+ different implementations coexist. OAuth.io fixes this massive problem by acting as a universal adapter, thanks to a robust API. With OAuth.io integrating OAuth takes minutes instead of hours or days.
OAuth2 and OAuth.io can be categorized as "User Management and Authentication" tools.
