To CHANGE Your Password: 

* log in with your current password
* click on MY SETTINGS
* enter your current password AND then also choose a NEW password

Or, if you do NOT know or remember your current password: 

on the LOGIN PAGE: just click on "FORGOT PASSWORD?"

You will then receive an email to reset your password.

IMPORTANT: please check your SPAM FOLDER afterwards.

These kind of emails unfortunately tend to land there oftentimes.

The link in that email will lead you to a page where you can reset your password.

Enter that new password you chose TWICE and hit "Reset Password."

You can now log in with your NEW PASSWORD. ;)
