If you have an inactive Yahoo username/email address, it could end up in someone else’s hands about a month from now. And that could create all kinds of havoc if the new owner of your old username decides to use it to try to recover old online passwords of yours that might still be associated with that Yahoo address.
Yahoo announced a new username wishlist tool today that allows existing Yahoo account holders to put in claims on up to five inactive usernames. It comes about a month after Yahoo announced plans to recycle usernames.
