title: .NET Core Identity vs IdentityServer4
body: <p><strong>The question: Should I use .Net Core Identity or IdentityServer 4 with Identity</strong></p>
  
  <p>I need to build app with login/register functionality and allow users to use APIs to import/export data from my software. I also want to have external logins like google, twitter, etc.</p>
  
  <p>And I'm not able to understand why would I need Identity Server when all things can be done using only Identity. </p>
  
  <p>Why would I need or want IdentityServer ? I just need to get work done right and  as simple as possible.</p>
