Unable to reset password for admin access

Hi, I am the club admin for our toasthost website. I recall receiving a prompt to change the admin password, but waited to do so until I spoke with the other officers.  Now, I can't figure out how to do so. Of course, this year of all years, I am not serving as an officer. I've managed the club website for over 10 years. Thank you for your assistance. Eileen Grodziak https://lvtoastmasters.org
