title: Azure AD B2C - user type 'Guest' or 'Member'
body: <p>Can someone explain the differences between userType <code>Guest</code> and <code>Member</code>? What are consequences when creating a user in B2C? Can't find it in the docs.</p>
  
  <p>I create a user with Graph API and <a href="https://msdn.microsoft.com/library/azure/ad/graph/api/entity-and-complex-type-reference#user-entity" rel="nofollow noreferrer">here's the docs for User entity</a>. It has <code>userType</code> in there and it can be <code>Guest</code> or <code>Member</code>. But I'd like to understand this difference.</p>
