Hi @tads8799. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In refine, you can control access to different parts of your application using the accessControlProvider and the CanAccess component. The accessControlProvider has a can method that checks if a user has access to a certain resource based on their role. Here's an example of how you can implement this:

<Refine  
 ...  
 accessControlProvider={{  
 can: async ({ resource, action }) => {  
 let can: boolean = false;  
 const stringifyUser = localStorage.getItem('refine-user');  
 if (stringifyUser) {  
 const { role } = JSON.parse(stringifyUser);  
  
 switch (role) {  
 case 'admin':  
 can = ['login'].includes(resource);
 break;  
 case 'user':  
 can = !['login'].includes(resource);
 break;  
 }  
 }  
 return Promise.resolve({ can });  
 },  
 }}  
/>

<Refine  
 ...  
 accessControlProvider={{  
 can: async ({ resource, action }) => {  
 let can: boolean = false;  
 const stringifyUser = localStorage.getItem('refine-user');  
 if (stringifyUser) {  
 const { role } = JSON.parse(stringifyUser);  
  
 switch (role) {  
 case 'admin':  
 can = ['login'].includes(resource);
 break;  
 case 'user':  
 can = !['login'].includes(resource);
 break;  
 }  
 }  
 return Promise.resolve({ can });  
 },  
 }}  
/>

In this example, the can method checks the user's role and the resource they are trying to access. If the user is an admin, they are allowed to access login route. If the user is a user, they are not allowed to access login route. You can also use the CanAccess component to wrap the parts of your application that you want to control access to. Here is an example of how you can use the CanAccess component to control access to the 'login' route:

<Route path="login">
  <CanAccess resource="login">
    <LoginComponent />
  </CanAccess>
</Route>

<Route path="login">
  <CanAccess resource="login">
    <LoginComponent />
  </CanAccess>
</Route>

In this example, the LoginComponent will only be rendered if the user has access to the 'login' resource.

prevent access the whole app if there's no user @kapa.ai , remove refine login page since I use 3rd party authentication to go directly to the CRUD page

Let me check the knowledge base for you. One moment! :books: ---------------------- In refine, you can control access to your application using the Authenticated component and the useIsAuthenticated hook. If you want to prevent access to the whole app if there's no user, you can wrap your routes with the Authenticated component. This component will check if the user is authenticated and if not, it will render the fallback prop. Here's an example of how you can use the Authenticated component:

import { Authenticated, Outlet } from "@pankod/refine";
import { Route, BrowserRouter as Router } from "react-router-dom";

const App = () => {
  return (
    <Router>
      <Authenticated
        children={<Outlet />}
        fallback={<Route path="/login" element={<Your3rdPartyLoginComponent />} />}
      />
    </Router>
  );
};

export default App;

import { Authenticated, Outlet } from "@pankod/refine";
import { Route, BrowserRouter as Router } from "react-router-dom";

const App = () => {
  return (
    <Router>
      <Authenticated
        children={<Outlet />}
        fallback={<Route path="/login" element={<Your3rdPartyLoginComponent />} />}
      />
    </Router>
  );
};

export default App;

In this example, the Outlet component (which contains your routes) will only be rendered if the user is authenticated. If the user is not authenticated, the Your3rdPartyLoginComponent will be rendered. If you want to remove the refine login page and use a 3rd party authentication, you can do so by replacing the AuthPage component with your own login component in the fallback prop. Please note that you need to implement your own authProvider to integrate with your 3rd party authentication service. The authProvider is an object that provides methods for handling authentication tasks such as login, logout, and checking if the user is authenticated.
