ASP.NET OAuth Single Sign-On (SSO) module gives the ability to enable OAuth Single Sign-On for your ASP.NET applications. Using Single Sign-On you can use only one password to access your ASP.NET application and services. Our module is compatible with all the OAuth compliant Identity providers. Here we will go through a step-by-step guide to configure Single Sign-On (SSO) between ASP.NET and OneLogin considering OneLogin as OAuth Provider.
