How can I delete multiple Yahoo! accounts at one time easily without remembering the passwords and start over fresh with just one permanent one?
This will have to be done for each account individually.
You will need to contact Customer Care to request for this. As their are ways to recover an account, I recommend you try and recover it by logging in with your password, or using the Forgot Password feature in order not to waste their time.
If you cannot recover the account or it has been hacked then contact them.
Once logged in you can delete the account following these steps:
- Sign in to the Yahoo account termination page.
- Read the info on terminating your account.
- Use the on-screen prompts to continue.
