Which is why we advise on 2 factor authentication. Although, I have to be honest, if you have that many coming and going admin, you have more issues with security than hiding a folder
Stenagraphy - Noun - the practice of concealing messages or information within other nonsecret text or data.
I'm not actually sure the defininition of Stenagraphy states it is a secure measure. However, lets skip past that part and assume it absolutely is.
What my colleague stated was "Security through obscurity isn't the best method of security." This is not in any way the same sentence as "security isnt a secure measure". Its probably not wise to misquote people, as it can cause confusion for others, and lead them believe we have said things that we actually haven't.
What Jim said there is correct. Its not the best method of security. No matter whether or not you want to have security by obscurity or not, it doesn't make it the best method.
Listen, we get it. You would prefer to have this option. However this has now already been removed in version 5, and we advise on 2 factor authentication.
