Explain user authentication in Django

Django comes with an authentication system configured by default to handle objects like users, groups, permissions, and so on. The authentication system’s core is made up of user objects. It not only authenticates users but also authorizes them. Aside from using the default, we can employ a variety of web apps instead of using the default system to enable more user authentication. The default system objects are as follows:

• Users
• Permissions
• Groups
• Password Hashing System
• Forms Validation
• A pluggable backend system
