I would like to redirect to another url when auth failed.  
Any idea please thanks!

```plaintext
plugins
  myplugin
    lib
      auth
        my_auth_controller.rb
          def after_authenticate(auth_hash)

            if not auth
              redirect_to "https://example.com"
            end 

            result = Auth::Result.new
          end

```

1. In your code, you have the **if not auth** condition, but there is no corresponding **else** statement.
2. The **redirect\_to** method should be used within a controller action. If you’re using it in a separate method like **after\_authenticate** , make sure it’s within the scope of a controller.  
So here is the correct code.

```plaintext
def after_authenticate(auth_hash)
  if not auth
    redirect_to "https://example.com"
  else
    # Authentication succeeded, continue with the authentication process
    result = Auth::Result.new
  end
end

```

The result world be, If the authentication fails **auth** is not true, it will redirect to “[https://example.com](https://example.com/)”. Otherwise, if authentication succeeds, it will continue with the authentication process.  
To verify, You may check browser developer tools to inspect network requests and redirects or use any online tool such as [redirect checker](https://redirectchecker.com/) This can help you identify redirection issue and status code.
