If you cannot remember your web-account password, you can start the process of resetting your password by submitting the email address that is associated with your account.
If the submitted email address is associated with a valid web-account, the system will send a special link to your inbox that you can use to ask the website to reset your password. The special link will expire 5 minutes after it is sent. Your password will not be changed unless you use the special link.
(Note that this option is not available for web accounts that are linked to LIBC network accounts through Active Directory)
