Every time I log onto Facebook, it asks me for my phone number. I skip that step. And each time I do that, I am reminded that my security status on this social networking Web site is low.
I fail to understand how my phone number can make my account more secure. On the contrary, I would rather give out as little information to Facebook, Twitter, and so on, as possible. It’s bad enough that I get so many marketing calls. Putting my phone number on my profile would mean getting some more of those pesky marketing calls. Moreover, I would be giving out more information to people who I do not know, therefore don’t trust (the security settings notwithstanding; because I do not understand cyber world and cybercriminals well enough).
