To change a Yahoo Password, visit Yahoo: Change Password.

Changing a Yahoo password causes all the passwords on Yahoo’s personalized services to change. These personalized services include:

  • Yahoo! Mail
  • Yahoo! Messenger
  • Yahoo! Chat

The instructions to change a Yahoo password will only work if the user knows his/her current Yahoo password. If the Yahoo password is lost, please refer to How does Yahoo password recovery work?
