Sign in with a Ymail or Rocketmail account

When you sign in with a Ymail or Rocketmail username you'll use the entire email address for your username, not just the part before the @ symbol.

For Example:

If your ID is "johnsmith75" and you have a "ymail.com" email address, you'll  enter the username "johnsmith75@ymail.com" to sign in to your Yahoo account.

If your ID is "johnsmith75" and you have a "rocketmail.com" email address, you'll  enter the username "johnsmith75@rocketmail.com" to sign in to your Yahoo account.
