This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


OAuth is the only protocol supported by Salesforce that allows you to use the standard login page. The other methods of authentication are SOAP (which you provide your own custom UI for) and SAML (which you provide a server that users authenticate against), neither of which have the capability of using the standard login page. If you want to use the Salesforce Login page, you must use OAuth, and therefore must use a Connected App.
