Hey there,

I am really sorry for the delay of this reply as it is a weekend for us here.

Currently we do not have translation for other language yet because we still looking for another alternative language translation platform.

But you can copy this English translated file from JoomlaFolder/language/en-GB/en-GB.com_easyarticles.ini then manually translate it to brazilian portuguese language then rename it to this file name pt-BR.com_easyarticles.ini

After that put this file pt-BR.com_easyarticles.ini into this file location. JoomlaFolder/language/pt-BR/..
