If you'd like to reset your password, you can update it while you are logged in by clicking on your profile menu in the top menu, and selecting 'Change Password'.
You then need to enter your email so you can receive a secure code. Once you click 'Send secure code' you should receive an email within 2 minutes. Keep your screen open.
Return back and enter the secure code and click 'Verify code'. If you did not receive the code you can attempt to send another.
