Change Password to Admin

I desperately need to change the password to the admin area. The login page offers the forgot password option, but I'd like to change it to something specific. My manual asays that after I login, I can change it from the “Authentification Box” (section 5.6 Authentification, p.77/133 for v. 1.3.x). For the life of me, I do not see an authentification box or any way to call one up. It just opens to the order and user statistics with the management options to either side.

Any ideas?

What version are you running. You reference 1.3.x… If you're on V2, when you login to your admin panel, just click Users/Administrators and select Admin and change the password on the profile page.
