I have a problem with Google. It builds a profile of you and then adjusts your search results to fit that profile. When I'm doing an online search, I want to get as broad a range of results as possible, not the results that Google's algorithms think I might be interested in.
Several years ago I began to realise that my search results on Google were really poor, and I looked up the profile it had on me. It seemed to think I was a 65-year-old man. I think this was because I went through a phase of looking at 1940s jazz videos on YouTube! It explains why I kept getting ads for "Tena Men", a range of incontinence pads for men!
I didn't bother to enlighten Google. Instead I started using Startpage as my main search engine. I'm not sure if this is possible on a Chromebook. I have an Android tablet, and Google is always the default search engine.
So while I think it's good for young kids to learn how to keep a password, I'm not a big fan of logging on and having an online profile built around me. For that reason again, I only use the old versions of Microsoft Word - the current version can only be used with an online connection. That seems crazy to me for a word-processing platform.
I do log in to various online platforms, but I try not to share too much detail about myself online.
