Just came up with my father again.
He blames me that mother forgot her phone’s and Google password because I recommended against it being a word.
I mentioned encryption, “not necessary unless you’re doing something illegal”.
When mentioning lack of privacy with targeted advertisements, he said that he actually really likes them, because he bought a couple of things he wanted for years.
I don’t really have good arguments.
As far as I know, the thing is that randomly chosen words will be more secure because there’s simply too many words. However, sentences will be more predictable. And a single word will give quick access to someone with a sufficient wordlist.
Honestly, I don’t remember what exactly my recommendation was, just that I recommended against something quite simple (common word), and that she shouldn’t tell me or anyone else what it is.
Edit: but I am not a professional, so don’t use me for advice.
