A customer account system requires more than login and registration. It needs authentication, authorization, session management, account recovery and protected data access.

Secure Account ArchitectureAuthentication

Design authentication and authorization together so customers can securely access only their own data.

Key Takeaways at a Glance:

  • Authentication verifies identity while authorization controls access.
  • Password recovery and session management are part of the account system.
  • Customer data should be protected server-side.

Customer login changes a website from a public information system into a user-facing application.

The application now needs to know who a visitor is, what they are allowed to access and how their account is protected.

That makes authentication architecture an important part of development.
