You can get your new password if you add an alternate e-mail adress (password recovery/reset e-mail adress) using METU Alumni User Account Management https://alumniaccount.metu.edu.tr/ web page. To do so, you need to have a registered recovery e-mail. 

If you have a registered e-mail address, click on "Forgot password?” link

After filling the form, click on the “send e-mail” link. You should click the link sent to your e-mail address to reset and activate your new password.
