Signal Public Username Testing (Staging Environment)

Signal’s move to test public usernames in a staging environment is seen as a way to reduce reliance on phone numbers for identity, improving privacy for users who don’t want to expose their real number. Commenters weigh this against longstanding usability and security tradeoffs in secure messaging, comparing Signal’s strict end-to-end encryption and limited sync options to Telegram’s richer feature set but weaker default privacy model. The change also raises design questions around abuse prevention, account recovery, and support for multiple personas under different usernames.

Signal Public Usernames & Phone Numbers

  • New feature lets users share a username instead of a phone number; phone is still required for account creation.
  • It appears you can hide your number from groups and disable discovery by phone, using only the username in practice.
  • Some see this as a strong privacy improvement, especially for temporary or asymmetric relationships (e.g., young women sharing contact info).
  • Others are disappointed that the phone-number requirement itself is not being removed.

E2EE, Usability, and Multi-Device Sync

  • Ongoing tension: strong E2EE and minimal metadata vs. convenience features like chat history on new devices.
  • Some argue E2EE is an “anti‑feature” for most users because losing a device or key means losing history.
  • Others say multi-device E2EE with sync is clearly possible (citing Signal, Wire, iMessage, WhatsApp), just hard to implement well.
  • Signal’s backups: Android has local backups; iOS relies on device‑to‑device transfer. “Secure Value Recovery” exists but does not yet provide full backups, and its exact scope is debated.

Signal vs. Telegram

  • Telegram praised for planning, features, open-source clients, multi-device support, channels, and resistance to some government pressure.
  • Criticisms: no default E2EE, custom crypto (MTProto), messages stored in the clear on servers, contact upload by default.
  • Dispute over where Telegram’s servers “really” are and how much Russian influence matters; some see it as effectively a Russian company regardless of formal HQ.
  • Some users consciously trade away E2EE to get Telegram’s multi-device sync and web access.

Identity, Personas, and Username Design

  • Strong interest in using different identities for different communities, to avoid cross‑linking profiles and to separate “serious” from casual activity.
  • Concerns about username collisions and misdirected communication, likened to generic Gmail addresses that receive large volumes of others’ mail.
  • Signal’s Discord‑style username plus 2‑digit discriminator is criticized as too small a space (only 100 variants per name) and conceptually awkward.

Community Site Authenticity

  • Some were wary of signalusers.org until they found it linked from Signal’s official site and GitHub; it’s described as an “unofficial community forum” but apparently endorsed for discussions.
