C'mon folks, it's Twitter...
I like Twitter, and have always found that I can manage it to be useful and not too annoying. Miles ahead of Facebook for instance. However...
I guess it's the result of several decades on-line, but I have come to accept that nothing on-line is ever entirely secure. No matter how careful you might be, you're relying on other people to run the back-end, and you have no real way of knowing how honest or competent they are. Or who will buy out the company next month and destroy it.
Consequently I have some things, like banking, that get big-ass complex passwords that I'm confident won't likely be figured out. Others, like the electric bill get something more mid-range. I mean seriously, if someone hacks into my Nova Scotia Energy account what can they really do?
Beyond that the stuff like Twitter and Facebook get easy to remember, recycled passwords. I've had multiple Facebook and other accounts over the years, and there are no social media sites that I wouldn't happily nuke if they got taken over by some evil-doer.
And all of this is handled at my end, from my brain, not by hackable outfits like LastPass. Of course I also pay attention to what kind of information is posted to various platforms. Things that I'll exchange over email do not get posted to Facebook or Twitter.
All of this reflects a belief that none of these companies really care about my privacy or security. 2FA and fingerprint scans are nice, but none of them represent a real change from password practices of two decades ago. They are all still a single point of failure, and one that will inevitably be defeated. The best that we can do is keep the really important stuff off-line, even on paper, so that it can't be stolen.
And that, ultimately, is the point. Anything that you store on-line is by definition out of your control. You are trusting a person or corporation to take care of your best interests. Thinking that you're being secure is at best naïve, and at worst a recipe for disaster.
