unable to disable password based authentication for ssh

Hello,
I am trying to set up ssh to use public key only. The guides said to set the config as:
and restart the ssh server, which I have done. My entire config is:
Is there something I am missing? When I do ssh -v pi on another machine, I can still get a password prompt and it says:
Authentications that can continue: publickey,password
which makes me think I am missing something. I restart with sudo systemctl restart sshd, but have also tried rebooting, and neither results in the expected outcome.

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.
