This is why you don't use the same password for multiple accounts. For example if I used the same email and password for my Facebook account as my Apple account then both would be compromised. This is one common way people get their accounts "hacked" then they'll blame whatever account for this. LOL
I would probably argue a "middle" approach, which is "just as secure" Not entirely, but the result would be the same..
You use one "complex" password everywhere
Yes, it would get out because, leaks etcc.. but due to the complexity it will be just as strong.
Not what i do, it it would serve the same purpose.... At least yo only have to keep (one) complex password, and not many (which would be the ultimate goal)
