I started a Yahoo! mail account a while ago. This was meant to be just a throwaway/spam email account. However, because it was easy to pass around, I ended up depending on it quite heavily. Since I didn't pay attention while filling the account creation form I am wondering if it is possible/how to change your Secret Question's answer.
How to change Yahoo! account Secret Answer?

I no longer see a Secret Question for you to answer in order to get a password changed.  They now verify it is you by using a secondary email address to send you a code or they will text you a code to your phone number to verify it is you.  Those are both in the upper right of the screen under the gear and then account info.  From there you go to account security.  From here you can add a phone number to which you can receive text messages.  If you chose you can also add a secondary email so you can get verified this way as well.
