Set Challenge Word
This form will set a challenge word for all of your accounts. (If you have multiple accounts, you only need to submit one challenge word for one account and it will apply to all of your accounts.)
Your challenge word will be used to verify security-related changes to your account, such as changing your password. Once set, your challenge word may not be changed. Do not lose or forget your challenge word.
Your challenge word must be a single English word, at least 5 letters in length, containing no special characters (hyphens, etc). Do not use your account name, first or last name, or organization. Some words may be rejected if they are too common or obvious. Case is ignored.
