Make sure you still have access to the mailbox of the email address that you will use to change your password.
Disable any service that might block messages from reaching your mailbox.
Wait for the password reset link in your inbox. Take a look at your junk/spam folders to make sure the reset link did not end up there.
You can only submit a password change request one at a time. You are not allowed to file multiple requests as this will delay the process of sending your password reset link.
