How can I change the question Yahoo asks me if I forgot my password?

Question

I changed my mail and messenger password and someone is still signing me in on another device. I don't know how, but someone knows the answer to my test question. (the one they ask you when you forget your password) I've had my account for 6 years or so, and I don't want to make another one. I'm happy with things the way they are. I'd appreciate an answer or a link to someone who has an answer.
