# Globally Enforce Authentication

If there is no part of your app that can be accessed without being logged it you can make oidc-spa automatically redirect your users to the login pages when they are not authenticated.  

Note that in this mode you don't have to check `isUserLoggedIn` (you know it's true), or `useOidc({ assertUserLoggedIn: true })`(you know that's the case).

```typescript
import { createOidc, OidcInitializationError } from "oidc-spa";

try{

const oidc = await createOidc({
    // ...
   isAuthGloballyRequired: true,
   // Optional, the default value is: location.href (here)
   // postLoginRedirectUrl: "/dashboard"
});

}catch(error){
    const oidcInitializationError = error as OidcInitializationError;
    console.log(oidcInitializationError.message);
    console.log(oidcInitializationError.type); // "server down" | "bad configuration" | "unknown";
}
```

{% endtab %}

import { createReactOidc } from "oidc-spa/react";
