I have been hacked and can not access my Yahoo account?

It sounds like you are receiving is called "Second sign-in verification," and it is designed to protect your account from unauthorized access. You can clear the prompt by having a verification code sent to your non-Yahoo! alternate email address or mobile number on file. If you don't have either of these options, you can contact the Account Security team by filling out the following Help form:

http://io.help.yahoo.com/contact/index?l…

Please submit a request on this issue by selecting Yahoo! Accounts as the product, suspicious activity as the category, and received security warning prompt as the subcategory.

Note: Be sure to completely fill out the help form so that the support team has all of the information necessary to assist you.

I hope this helps!
