I received a letter from Codeforces recently. It told me someone logged into my account.I searched the given IP and found that it came from Singapore,but I lived in China. I changed my password immediately. Who's that and what should I do?

stop use VPN
Could you please explain
Have you been using a VPN? If so you don't have to be bothered. If not then you do have to be bothered.
Actually I’m not. Do I need to be so worried about this?
Maybe somebody guessed your password. Just make sure you use a strong password.
I know. I think I must make it much stronger. Thanks for your comments.
