forgotten my yahoo password how do i retrieve or change it?

• Have you lost or replaced your phone and the number is no longer available?
• Did you forget your password?
• Are you getting a message that the account is not there when trying to sign in?
• Did a hacker change all recovery information?

You can only regain use of your account if there is a current recovery email or phone even if a hacker changed it. You must have a recovery email or phone. If you only have one and can't use it there is no other method other than what the next paragraph indicates.

There is a new paid service called Yahoo Account Pro. Details at this link. https://productcentral.yahoo.com/products/yahoo-account-pro-help
It is possible that they can be of help but there is no guarantee that paying for the service will solve your problem. There is no other paid service. This is only available in the US.

Security questions were eliminated many years ago and are only used for old accounts where there is no recovery email or phone. You can remove them now under account security. They may have already been removed. For details go here. https://help.yahoo.com/kb/account/delete-havent-removed-automatically-sln4842.html

If the account was closed for non use for a year or for TOS violations such as being underage in your country it can't be recovered. You will see a message that the account is not there.

To recover an account or to get a list of accounts associated with a recovery phone number or email address go here. https://login.yahoo.com/forgot

Do not use this method to just change your password if you know the old one. Just go to Account Security under Account Info or go here. https://edit.yahoo.com/config/change_pw
