OK, - this one is a bit “tricky” but the way I have found is - click on your avartar (the cat in your case) at the top right hand corner of the page.
From the pulldown that appears click on profile (the top entry in the list).
Now on the next screen on the thick black bar click on the preferences button and there you can change several things including your password. To do this click on the “send password reset email” and check your email - it includes a link that you need to click to be able to go and set a new password.
Told you it was a bit tricky!
P.S. For clarity - this is the REFLECTOR password reset as you requested, NOT the new website account and password.
