Está ocorrendo erro de acesso ao banco de dados mesmo após eu definir a tag password:

    <security>
                    <user-name>root</user-name>
                    <password>123</password>
                </security>

coloca tua configuração do datasource lá do wildfly, o login e senha do teu banco de dados local está correto? o driver foi criado corretamente? Um exemplo de um datasource meu configurado e funcionando corretamente para o postgres(wildfly/standalone/configuration/standalone.xml):
