I could have just as easily said 666 for his purpose of temporarily CHMODing .htaccess but didn't.
And again, you didnt. Why? Until you can provide a reason why you offered up an alternative within the context of answering something that specifically asks if 666 is insecure, we are going to go round and round.
Need a metaphore/allegory/whatever:
If you ask me if you should buy a Jeep but express that you are worried about gas milage, and I answer with .. "An accord will get you to the same places".. you can see very clearly I am inferring that one has better gas milage than the other.
And dont presume to think that the OP understood that 646 is basically the same thing. he or she certainly knows now, since Ive made my point.
Thats the whole reason I even bothered with challenging you - you either did presume, or you didnt realize and are now simply too stubborn to admit that you thought that you were offering a more secure solution, however temporary it might be.
Now, I gave you a pass, and basically let this go with an "ok, he just didnt realize that dealing with new users about security takes a little more wording".. but if you want to continue, we surely can..
