We use the alternate email address to send you information regarding your account, updates regarding Yahoo!, and a new password if you ever need one sent to you. We have found this to be an effective tool, especially if someone is having problems with their Yahoo! Mail account.
However, if you don't currently have an email address, you can leave this field blank when you register for a Yahoo! Mail account.
Please Note: If you don't enter an alternate email address for your account, you will only be able to receive a new password by either your mobile phone or providing the Security Answer to the Security Question you entered during registration. If you forget the answer to your Security Question and do not have an alternate email address or mobile phone number listed on your account, you will not be able to receive a new password.
