I've created a new user for FTP.

useradd -g www-data -d /srv/www/vhosts/project/ black

I made a mistake, I actually need the user to be in the group www.

How can I change the group?

You can use:

sudo groupadd www # Add a new group, if not exists
usermod -a -G www black # Add the existing user black to www
usermod -g www black # Change the primary group of black to www

To confirm that it has been added:

groups black

From removing user from secondary group, in this case www-data group:

gpasswd -d black www-data
