That seems highly unlikely. Thus, there seems to be a trade-off between security and convenience, and the average user must make a choice. Nevertheless, the average public prefers some modicum of convenience over these types of draconian security measures. Where this line between security and convenience lies seems highly dependent on the subject matter. People are willing to sacrifice a few extra minutes at the airport, so that luggage and carry-on items can be searched for weapons and bombs.
People perceive e-mail to be a convenient method of communication.
The reason these are not popular options is that they are inconvenient. We could make our software package easier to use by not requiring a password every time an e-mail is received, but then you lose some security. This, too, is a trade-off. Rather, we take some liability away from those sending e-mails. For instance, if two employees of a corporation are exchanging corporate information through e-mail, they can use our service.
