## Encrypted messaging

The first move, the one that protects you fastest: leave WhatsApp, Messenger and Telegram for a genuinely encrypted (ideally open-source) messenger.

  <Fragment slot="what">
    An encrypted messenger for your texts, calls, video and groups. The direct replacement for
    WhatsApp, just as simple.
  </Fragment>
  <Fragment slot="why">
    End-to-end encryption by default, non-profit, an audited protocol that is the world standard.
    Almost no metadata kept, and the team has pledged to leave the EU rather than install scanning.
  </Fragment>
  <Fragment slot="who">
    Everyone, starting today. It's the first and most useful step. One catch: a phone number, which
    you can hide behind a username.
  </Fragment>
  <ol slot="install">
    <li>
      Install from <b>signal.org</b> (App Store, Google Play, or the direct APK on Android).

    <li>Confirm your number by SMS, then set a PIN.</li>
    <li>
      Settings &gt; Privacy: create a <b>username</b> to hide your number, and turn on{' '}

  </Fragment>
  <Fragment slot="what">
    An encrypted messenger with no account, no number and no identifier. You connect by sharing a
    link or QR code.
  </Fragment>
  <Fragment slot="why">
    By design, even the servers can't know who talks to whom. It's currently the strongest option
    against metadata correlation.
  </Fragment>
  <Fragment slot="who">
    Pseudonymous accounts, sensitive contacts, high-risk. A bit younger than Signal, with a few
    rough edges.
  </Fragment>
  <ol slot="install">
    <li>
      Install from <b>simplex.chat</b> (F-Droid, Google Play, App Store or APK).
    </li>
    <li>
      Pick a <b>local</b> display name (never your real name: it stays on your device).
    </li>
    <li>
      To add a contact, share a <b>one-time invitation link</b> or a QR code.
    </li>
    <li>Turn on the passcode lock, and (advanced) configure your own SMP servers.</li>

  <Fragment slot="what">
    Signal-grade encryption, but with no phone number and onion routing.
  </Fragment>
  <Fragment slot="why">
    Your identity is a random "Session ID." Traffic goes through a decentralised network (Lokinet)
    that sharply reduces metadata.
  </Fragment>
  <Fragment slot="who">
    When a phone number is a liability. Smaller ecosystem, best kept for conversations that matter.

  <ol slot="install">
    <li>
      Install from <b>getsession.org</b> (all platforms).
    </li>
    <li>
      "Create account" generates your Session ID and a <b>recovery phrase</b>.
    </li>
    <li>Write the recovery phrase on paper: it's the only key to your account.</li>
    <li>Share your Session ID (or QR) with your contacts.</li>

  <span class="lab">Against Chat Control</span>
  <p>
    Prefer <strong>open-source</strong> apps <strong>outside the big US platforms</strong>, whose
    teams have publicly pledged to leave the EU rather than install client-side scanning (Signal
    has). Reminder: if the OS itself enforces scanning, the app can't help, hence section 12.
