Hello. My name is***** to JustAnswer. I'm reviewing your question now, and will post back with your reply momentarily.
Do you have a yahoo account when you say trying to get your id/password?
have you forgotten both?
Or do you need to actually make and get a yahoo id/password ***** forgotten the password ***** your yahoo?
When you respond, i will be more than happy to help resolve your issue by communicating back and forth.
