I really enjoy almost all nautilus articles I've read so far, and they're linked pretty frequently here. So just now, I finally decided to just buy a yearly subscription to support them. All fine and dandy, easy checkout, whatever. But then after purchasing I get an email from them that says that to sign in and view content, only the email used is required, no password needed (account details are unavailable without password). I'm now thoroughly confused because even the worst security models I've seen at least pretend to have a password. What reason would that have for this security model?
