Now you can securely link multiple phones to one Signal account
What's happening
Signal now allows users to link multiple phones to a single account, expanding beyond its previous support for only computers and tablets. This means a user can access their encrypted messages across several mobile devices simultaneously.
Who's involved
Signal is an open-source encrypted messaging platform that provides instant messaging, voice calls, and video calls with end-to-end encryption. The Verge is reporting on this new feature rollout.
Why it matters
This feature addresses a practical limitation for users who carry multiple phones or regularly switch between devices, making the platform more flexible for modern usage patterns. It strengthens Signal's competitive position against other messaging apps by offering device parity previously available only on larger platforms.
The story
Signal, the encrypted messaging service, is expanding its multi-device capabilities to include linking multiple phones to a single account. Previously, the platform allowed users to connect computers and iPads to their primary phone number, but the service now extends that functionality to additional Android phones and iPhones. According to The Verge, this update lets users check and respond to messages across all linked devices without being restricted to a single phone.
The feature represents a significant usability upgrade for Signal users who maintain multiple mobile devices. Someone might use both a work phone and a personal phone, or regularly switch between devices; the multi-phone linking capability now allows all these devices to stay synchronized with the same account and phone number. Messages received on one device automatically appear on all others, ensuring users never miss a conversation regardless of which phone they have in hand.
Signal's approach to multi-device support relies on its end-to-end encryption infrastructure, a method of implementing secure communication where only the sender and intended recipient can read messages. This means the system provider, telecom providers, internet providers, or malicious actors cannot access the cryptographic keys needed to read or send messages. The challenge of extending multi-device support while maintaining this security model likely contributed to the time it took to add phone-to-phone linking compared to the earlier computer and tablet functionality.
The timing of this feature comes as messaging platforms continue to compete on both security and convenience. Signal has built its reputation on privacy-first design, and adding practical features like multi-phone support helps make that privacy accessible to users with more complex device ecosystems. The feature maintains the platform's commitment to end-to-end encryption across all linked devices, ensuring that the security model remains unchanged even as usability expands.
For Signal's user base, which includes privacy-conscious individuals and organizations handling sensitive communications, the multi-phone linking option removes a significant friction point. Users no longer face the choice between device convenience and account security. The update demonstrates Signal's continued evolution as a messaging platform, balancing the practical needs of modern mobile users with the security guarantees that define the service.
