# Protect Views

Logging in and out ensures that only **authenticated users** can access the application. However, most business applications require more than just authentication—different types of users often have varying levels of access.

In role-based applications, users are assigned specific *roles* that determine what data they can access and which actions they can perform. To enforce these restrictions, you must implement proper **authorization** for your views.

The following guides show you how to protect views in Vaadin applications and restrict access based on user roles:
