Hello,
I am not a maintainer of this repo but I made your request work on my computer by adding this config line AuthenticationMethods "publickey,password"
to the /etc/ssh/sshd_config file and restart the container.

There is currently no option to add it on the fly.

You can create a custom script in /etc/sftp.d that add the line for you in the config.
This script for instance is working if mounted on the container in /etc/sftp.d/forceauth.sh

#!/bin/bash    
    
if [ ! -v AuthenticationMethods ] ; then    
    AuthenticationMethods="publickey,password"    
fi    
    
if [ -z "$(grep AuthenticationMethods /etc/ssh/sshd_config)" ] ; then    
    echo lol    
    echo "AuthenticationMethods \"$AuthenticationMethods\"" >> /etc/ssh/sshd_config    
else    
    echo mdr    
    sed -i "s/AuthenticationMethods .*/AuthenticationMethods \"$AuthenticationMethods\"/" /etc/ssh/sshd_config
fi    

With this script in the container, you can even change the AuthenticationMethod with the AuthenticationMethod env var.
