2FA should IMHO be standard and not make headlines!
On the other hand and with the latest Synology private cloud hacks, I am not sure if 2FA makes that much of a difference for private cloud servers. 2FA cannot be used for all logins and the solution therefore are usually additional passwords with limited user rights, however, if there is a security issue, such limited user rights are usually sufficient …
Your mileage might vary, of course, but I agree more and more that hosting your own data is probably not the right solution for most users (and maybe even for most HN folks).
