Would you pay a one-time fee to register for a messaging app without a phone number?
Signal has released beta version 8.28 for Android, introducing an optional registration path that does not require a phone number. Users can now utilize a 32-character Account ID and a 64-character Recovery Key for identification.
Why it matters
This feature provides an alternative registration method for users who prefer to skip phone number requirements while maintaining the app's standard privacy protocols. It utilizes a one-time payment system to facilitate this privacy-focused account setup.
The registration process uses a 32-character Account ID and a 64-character Recovery Key, with the $2.99 fee processed via Google Play Services. The system relies on a zero-knowledge proof setup to maintain anonymity during the transaction.
The players
Signal
Signal is an encrypted messaging service known for its focus on user privacy and secure communication standards.
The details
Signal processes the payment through a zero-knowledge proof setup similar to its existing donation infrastructure. Users must manage their own Account ID and Recovery Key as the company does not provide a recovery mechanism if these credentials are lost.
Timeline
September 22, 2026: Signal announced the new beta registration feature for Android users.
The Tech Race
This registration method follows the privacy-preserving architectural patterns established by Signal's zero-knowledge proof donation system. It signals a move away from legacy identity verification models that tie user accounts to telecommunications-linked phone numbers.
Android users participating in the beta can now register without sharing their phone number by paying a $2.99 fee through Google Play. Prospective users should be aware that losing the generated Recovery Key or Account ID will result in permanent loss of access to that account.
The takeaway
This development marks a significant shift toward decoupling digital identity from cellular phone numbers in encrypted communications. Users should prioritize the safe storage of their recovery credentials since the service provides no manual override for lost account access.
