Hi Po_Pandasan,

Did you try to follow the instructions of this article (the "What can I do if my Security Key is not working properly?" section): SW:TOR Security Key?

If yes and you still encounter issues, we invite you to directly contact the support team for additional verification. As your issue is about your security key, you should contact them by phone. Here is our article on how to do that: How to contact STAR WARS: The Old Republic (SW:TOR) support.
