Many of my online accounts nag me about the fact that I don’t have my phone number registered with them and that I should really do that for account recovery reasons. Yeah, no. My phone number is a closely held secret and I only give it out to family and friends. Random companies are not granted the that privilege.

And then, as this article points out, there is also the fact that mobile phone communications and number ownership are no way secure, have never been, and there’s not any evidence that they will ever be. /tinfoil
