One thing I noticed from using EACCREG is that every three (3) months it forced me to change my password without any encountered malicious activity. I believe its for the safety purposes for every taxpayer.
Since I am not good remembering passwords especially that you cannot repeat passwords that you already been used. I created a hard-copy or a fill up form wherein I can use it as reference of all my created passwords. Its really draining to create password and keep them be remembered.
Just like to share it to you how did I do it just in case my memory failed me.
