Laravel Sanctum | Delete current user token not working

Title: Resolving Issues with Token Deletion in Laravel Sanctum Authentication System Dealing with personal access tokens and user accounts can be challenging when it comes to implementing proper session management, particularly during login and logout scenarios. This blog post aims to address the common issues faced by developers while handling token deletion using Laravel Sanctum and provide effective solutions. To explain the issue in detail: a token should ideally get deleted when a user logs out of their account via your Laravel-based web application. However, you are encountering an error stating that the 'delete' method is undefined for Laravel\Sanctum\TransientToken objects. Moreover, the provided methods like auth()->user()->currentAccessToken()->delete(), auth()->user()->token()->revoke(), and auth()->user()->tokens()->delete() don't seem to work correctly in your case. To resolve this problem, you must first understand that Laravel Sanctum works with two token types: personal access tokens (PATs) and API tokens. While PATs are associated with specific users and can be created or deleted by the user itself, API tokens don't have a one-to-one relationship with users, making them more suitable for non-human actors like bots. In a Laravel Sanctum installation, when you generate a token via auth()->user()->createToken(), it is registered as an API token by default. To create a personal access token instead, you must explicitly call auth()->user()->createPersonalAccessToken(). Now, let's address the issue of deleting tokens during logout: 1. Create a new route group for handling tokens separately from your authentication routes. For example: Route::group(['prefix' => 'tokens'], function () { Route::post('/delete-token/{id}', [AuthController::class, 'deleteToken']); }); 2. Write a controller method to handle the token deletion request:

public function deleteToken(Request $request, $id) {
     try {
         $token = Token::find($id);
         if ($token) {
             switch ($token->type) {
                 case 'api':
                     $apiToken = ApiToken::whereId($token->id)->first();
                     $apiToken->delete();
                     break;
                 case 'personal_access':
                     $pat = PersonalAccessToken::find($token->id);
                     $pat->delete();
                     break;
             }
         } else {
             return response()->json(['message' => 'Could not find token'], 404);
         }
         return response()->json(['success' => true]);
     } catch (ModelNotFoundException $e) {
         return response()->json(['error' => 'Token not found'], 404);
     } catch (\Exception $ex) {
         return response()->json(['error' => $ex->getMessage()], 500);
     }
}

3. Update your logout method to use the newly created route:

public function logout(Request $request){
       Auth::guard('web')->logout();
       return redirect()->route('home'); // Replace with your desired destination after logout
   }

4. Implement an API endpoint to delete all tokens associated with the current user when they access the `/tokens/delete` route:

public function deleteAllTokens(Request $request){
       return auth()->user()->tokens()->delete();
   }

Now, when a user logs out, you can handle their token deletion appropriately. For more complex scenarios or specific requirements like deleting certain types of tokens or only the current token, feel free to customize the code accordingly. To conclude, always remember that Laravel Sanctum handles different types of access tokens in various ways. To delete a user's token during logout, you must carefully handle the type and scope of the token, as well as provide an appropriate API endpoint for handling your specific use cases. By following these guidelines, you can resolve the issue and create more efficient authentication systems in Laravel-based applications.
