Help with my email account on my laptop

Hello

Recently I changed my password for my Yahoo email account on my cell phone however I wasn't using my account on my laptop so I didn't access it. Last week I needed to use my email account on my laptop & even thou I was puting in the password I kept getting a message saying the account doesn't exist on Yahoo server. I however got access to my account online & saved update so in was able to go to my account but still can't sync, send or receive as it's now saying my account is unavailable.

Please help restore my account without me having to change my password again.

Thank you

Kind Regards
