Signal has expanded its multi-device support to include additional phones for the first time. Users can now link Android phones or iPhones to a single Signal account, joining previously supported devices like PCs and iPads.

The messaging app's multi-device feature allows users to check and respond to messages across all linked phones simultaneously. When linking a new device, Signal gives users the option to transfer an end-to-end encrypted copy of previous messages or start fresh. This selective message transfer addresses security concerns for shared, lost, or compromised devices. Users maintain full control over which message history—if any—syncs to each newly linked phone. Signal's approach differs from competitors by preserving encryption across all linked devices. The feature streamlines workflows for users managing multiple phones while maintaining the privacy protections that define Signal's service.
