DailyCred vs OAuth2: What are the differences?

Developers describe DailyCred as "Everything you need to manage users for your website or app". Everything you need is included: email verification, password resets, session cookies, and all the UI you need for sign in, and sign up. Skip all this work and get running instantly. If you already have a sign-in system, DailyCred sits side-by-side with the full power of user APIs and dashboards. On the other hand, OAuth2 is detailed 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.

DailyCred and OAuth2 can be primarily classified as "User Management and Authentication" tools.
