Signal's messaging application is in beta testing a new multi-device capability that would allow Android phones and tablets to function as secondary devices linked to a primary account. Previously, users wanting to access Signal on multiple phones had to register separate phone numbers for each device. This update would enable account holders to maintain a single account with synchronized message history across their Android devices, expanding on existing functionality that already supported linking iPads and computers.

The feature uses a QR code pairing process to establish the connection between the primary device and additional Android devices. For tablet users, Signal has developed a split-screen interface displaying the conversation list on the left side alongside the active chat on the right, with customizable elements to suit user preferences. The company has updated its support documentation in anticipation of broader release, though a specific timeline for general availability has not yet been announced.
