Everything is a field in drupal 8

• Node : author, created, changed, content type
• User : name, mail, password, roles

Advantages

• Formatters
• Configurable

Node Author

• Can use all entity reference
  • formatters

User Roles

• Can use all entity reference
  • Formatters 
  • Widgets
  •  
• Form : not configurable
• View: not configurable

Example Module : Real Author
