Vue Router navigation guards prevent unauthorized access by intercepting route transitions. You implement per-route, in-component, or global guards to check permissions and handle async checks before allowing entry into protected routes.

Handling Vue Router param changes uses the beforeRouteUpdate in-component guard. This intercepts param transitions within the same component, allowing you to fetch new data and update the view without forcing a full component remount.

Route meta fields store custom permission data on specific routes. Global guards read this meta information during navigation to centralize access control logic, ensuring consistent authorization checks across your application.

Vue Router redirect loops occur when auth guards redirect to a protected route repeatedly. Safe redirect handling requires checking the target route meta and stopping the loop by returning false or redirecting to an allowed page.

Yes, Vue Router beforeEnter guards apply per-route access control in Vue 3. These guards execute before entering a specific route, making them ideal for isolated authorization checks distinct from global navigation logic.
