MySQL Server 8.0.12 - An authentication plugin must be specified for new users - mysql

Question

I am trying to install MySQL Server (on Windows) using MYSQL community edition v8.0.12 in silent mode.
I first run
msiexec /i "mysql-installer-community-8.0.12.0.msi" /qn
Then
MySQLInstallerConsole community install -silent server;8.0.12;x64:*:type=config;
openfirewall=true;generallog=true;binlog=true;serverid=3306;enable_tcpip=true;port=3306;
rootpasswd=Unkn0wN;installdir="C:\MySQL\MySQL Server 8.0":type=user;username=foo;
password=bar;role=DBManager
MySQLInstallerConsole.exe execution log:

MySQL Server 8.0.12 - An authentication plugin must be specified for new users.
The error is: "MySQL Server 8.0.12 - An authentication plugin must be specified for new users."
Oracle doesn't seem to have updated the MySQLInstallerConsole reference parameters on its website, does anyone know how i can specify an auth plugin for MySQLInstallerConsole ?
For now i am just working around it by not creating user foo.
MySQLInstallerConsole community install -silent server;8.0.12;x64:*:type=config;
openfirewall=true;generallog=true;binlog=true;serverid=3306;enable_tcpip=true;port=3306;
rootpasswd=Unkn0wN;installdir="C:\MySQL\MySQL Server 8.0";datadir="C:\MySQL\data"

Answer 1

I discovered that using the auth_plugin setting with caching_sha2_password allowed for creating a user.
As of MySQL 8.0, caching_sha2_password is both the preferred and the default authentication plugin.
MySQLInstallerConsole community install -silent server;8.0.21;x64:*:^
type=config;openfirewall=false;generallog=true;binlog=true;^
serverid=3306;enable_tcpip=true;port=3306;rootpasswd=Unkn0wN;^
installdir="C:\MySQL\MySQL80";datadir="C:\MySQL\Data":^
type=user;username=foo;password=bar;role=DBManager;auth_plugin=caching_sha2_password
I've also been successful at installing other products like so
MySQLInstallerConsole community install -silent ^
workbench;8.0.21;x64:* ^
shell;8.0.21;x64:* ^
connector/ODBC;8.0.21;x64:* ^
connector/J;8.0.21;x86:* ^
connector/C++;8.0.21;x64:* ^
connector/NET;8.0.21;x86:*
