OPTION 1 - in case you DO know your current password, but want to change it:
* log in with your current password
* click on MY SETTINGS
OPTION 2 - in case you do NOT know/remember your current password:
on the LOGIN PAGE: just click on "FORGOT PASSWORD?"
You will then receive an email to reset your password.
IMPORTANT: check your SPAM FOLDER afterwards.
These kind of emails unfortunately tend to land there oftentimes.
That link 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. ;)
