title: I want to create a React App (website) with basic authentication
body: <p>I want to create a React Application (website) login page with <em>basic authentication</em> (username and password) but <strong>NO</strong> registration, <strong>ONLY</strong> login with a <strong>'</strong> private database <strong>'</strong> that redirects to a private route. Is this possible?</p>
  <p>(e.g - predefined users with name 'John' and password 'PasswordJohn' and user 'Jane' with password 'PasswordJane')</p>
  <p>Like a private API or something?</p>
