My point was, by the time you try all possible combinations the number of permutations spirals out of reasonable limits. “borntobewild” contains 12 characters. Just trying every permutation of capital and lower case gives 2^12 possible choices. There are 4 vowels and an “L”, so another 2^5 possible Leet or Texting shortcut variations. We haven’t even calculated the effect of spaces (if allowed) or punctuation in the middle or at the end. And that’s just one random phrase. Born to be Wild could spawn “Get Your Motor Running” or “Get Out on the Highway” (Hiway?) “Lookin(g) for adventure” and “Goin My Way”. Not to mention words made from the first letters of a line or two.
The point being, if you don’t use your pet’s name or one word from the dictionary, if how you choose your password is unpredictable and you don’t cleverly tell everyone your system, if you add in sufficient random alterations… then it’s about as safe as something can be when it’s only a password.
A systemic alteration based on website name is as safe as the likelihood that a hacker won’t discover your trick - by hacking multiple sites. But then, if they’ve hacked the whole password, then a single password wouldn’t be safe. the other problem is that many sites make you sign up with them, even for something as mundane as news articles - so you need either one generic password or a system for customizing them - or a new password for every site and a way to remember them. I’ve already seen the reverse problem, that “remember my password” as a simple shortcut results in people forgetting passwords. If you’ve changed emails in the meantime, yo are doubly screwed. Unless (as I’ve also seen) it’s your email password you’ve forgotten.
