 **We do not endorse or recommend some mainstream platforms for anonymity including the much-praised Signal which to this date still requires a phone number to register and contact others. In the context of this guide, we strongly recommend against using Signal if possible. The same recommendation applies to popular forks of Signal such as Molly (<https://molly.im><sup>[[Archive.org]](https://web.archive.org/web/https://molly.im)<sup>)**
