Why Login is required ?

Enabling a user to create an account and log in, is equipping them with security for and control over their information.

When a user can see the information they've given you in their user profile, they understand what you're using to connect with them. So when a user gets, for example, a promotional email, they know where it came from. They can simply go into their settings, change their email, check and unsubscribe from promotions.

Letting users see and control their data builds trust with users, which helps foster transparency about what information is stored by a company (especially when nobody reads terms and conditions).

Login is like your computer if you want that no one can access your computer except you, What you do you just add password to your account. Now only user who have your password can login into your computer.
