How do I implement a beforeEnter guard?

const routes = [
  {
    path: '/protected',
    component: ProtectedComponent,
    beforeEnter: (to, from, next) => {
      if (isAuthenticated()) {
        next();
      } else {
        next('/login');
      }
    }
  }
];

Can I use multiple guards for a single route?

Yes, you can use multiple guards for a single route. They will be executed in the order they are defined, and you can control the flow using the next function.

If a guard calls next(false), it will cancel the navigation to the route, and the user will remain on the current page.
