Mutual Authentication / two way SSL & OAuth

Question

Could you kindly help with following API authentication related questions:

1. Would Mutual Authentication / two way SSL described in this link works in combination with OAuth authentication?
2. Does Mutual Authentication work with REST API too?

Thank you.

Answer 1

Mutual Authentication & Oauth are two different authentication mechanistic.

Mutual Authentication: Allows client and server to identify and authenticate each other by using certificates. Ref: http://www.aboveandbeyondcloud.com/mutual-authentification-salesforce/

OAuth: also identify and authenticate user but using user/pass on salesforce site, so user do not need to reveal his password to 3rd part application. Ref: https://developer.salesforce.com/page/Digging_Deeper_into_OAuth_2.0_on_Force.com

And yes, once the authentication is done we can consume any API (REST, SOAP, Bulk ..etc)
