Once in your profile page, enter your new password in the two blank password boxes (Passwords must be at least 7 characters long, contain one uppercase and one lowercase character, one special character, and one number):

 

Scroll to the bottom of your profile page and click 'Submit.' 

 

At the top of your page, you should see a message similar to this:

 

You're done!
