&gt; ve has lots of vis personas<p>Are those typos?<p>You touched on the cyperpunk fantasy: using multiple online identities, all kept carefully separate from each other and from your real identity. (There&#x27;s an excellent short story called True Names that explores this idea.)<p>For the majority of ordinary, nontechnical people, there are lots of simpler solutions.<p>* Use cash. In Berlin, many ordinary people have an awareness of and distaste for government surveillance. People remember East Germany. One result is that lots of people will just pay for everything in cash. In most other western countries, the norm is to leave an electronic trail of every single shop you visit.<p>* Use Signal or WhatsApp. WhatsApp rolled out strong end to end encryption to a billion people--most of whom have no idea what a &quot;key&quot; is and only the faintest sense of what &quot;encryption&quot; means.<p>The lesson I take from those projects is that whenever we can ship transparent, easy to use encryption that our users dont have to worry about, its a massive win.<p>If your app allows users to talk to each other privately, consider adding E2E encryption. It&#x27;s the future.<p>If your app has some kind of cloud backup, like a password manager or a photo app, make sure that it&#x27;s encrypted with a key that you don&#x27;t have access to.<p>E2E comes with product tradeoffs. You may have to charge your users money, because you cant target ads against data you cant access. You&#x27;ll need to make an installed app rather than a webapp. But its worth it -- and I think someday, hopefully soon, users will demand it.
