Signal to enable phone-number-free registration using zero-knowledge proofs

A discussion on the Signal Users community forum has drawn attention for proposing a method to register for the encrypted messaging app without a traditional phone number. The thread, titled “Registration without a phone number,” has accumulated 66 up‑votes and generated 30 comments as users examine the feasibility and security implications of alternative verification approaches. The conversation highlights concerns about accessibility for individuals without mobile service, the potential for abuse, and the technical challenges of maintaining Signal’s end‑to‑end encryption standards while decoupling identity from a phone number.

The topic gained additional visibility after being linked on Hacker News, where the same post received comparable engagement, underscoring broader interest in privacy‑focused registration options. Participants in both forums are awaiting an official response from Signal’s development team, which could determine whether the platform will adopt optional, non‑phone‑based verification in future updates.
