DailyCred vs SimpleSAMLphp: 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, SimpleSAMLphp is detailed as "Application written in native PHP that deals with authentication". It is an award-winning application written in native PHP that deals with authentication. It supports some other identity protocols and frameworks, such as Shibboleth 1.3, A-Select, CAS, OpenID, WS-Federation or OAuth, and is easily extendable, so you can develop your own modules if you like.
