If you want more-secure methods adopted, they have to be easy to use. I find that encrypted PDFs are a reasonable option, even when reading on mobile. If I want to send myself something sensitive, I attach a password-protected PDF; then even if I open the “E-mail” on my iPhone, I am prompted for a password before I am allowed to view it. And frankly, I wish that web sites would stop trying to implement their own clunky mail-like “secure” messaging systems and just use password PDF. I hate receiving these “you have a secure message on oursite.com!” messages that are impossible to deal with on mobile (not to mention they appear very spam-like at first).
