title: Is OAuth2 Password grant type and client_credential grant types the same?
body: <p>As I understand before messing with Laravel Passport, <strong>password</strong> grant type is resource owner type and <strong>client_credential</strong> is for first party app, so basically routes protected with <strong>client_credential</strong> can access with token issues by itself,</p>
  
  <p>My problem is token issued from password grant type can access routes protected by client_credential, and routes protected by <code>api:auth</code> can't be access by <strong>client_credential</strong> token</p>
