Signal rolls out encrypted backups: $1.99/month for 100GB storage, free tier limited

Signal Introduces Encrypted Backups: Free Tier Up to 100MB, Premium at $1.99/month

Signal, the privacy-focused messaging app, has unveiled a much-anticipated feature: end-to-end encrypted backups. This new functionality offers a limited free tier for existing users and a premium subscription for enhanced storage and retention, marking Signal's first foray into paid features. The move aims to address the increasing costs associated with storing and transmitting large data volumes, particularly media files, a challenge for a non-profit organization that steadfastly refuses to monetize user data through advertising or data sales.

Understanding the New Backup Tiers

For free users, Signal now provides backups encompassing chat history and media files from the past 45 days, capped at a modest 100MB. This offers a foundational safety net for recent conversations. However, for those requiring more comprehensive backup solutions, a premium tier is available for $1.99 per month. This subscription unlocks full backups of up to 100GB, preserving chat history and media beyond the 45-day limit. These backups are generated daily by default, replacing the previous day's archive, ensuring users always have access to their most recent data.

Zero-Knowledge Security and Recovery Keys

Central to Signal's backup strategy is its commitment to user privacy, employing "zero-knowledge" technology. This means the backups are not linked to any specific user or payment method, ensuring a robust layer of security. To access and restore your backed-up data, users will receive a unique 64-character recovery key generated directly on their device. This key is the sole gateway to unlocking your encrypted backups. Signal emphasizes that losing this key means losing access to your backup permanently, as the organization itself cannot assist with recovery. Users do, however, have the option to generate a new recovery key should they wish.

Phased Rollout and Future Plans

Currently, the encrypted backup feature is in beta for Android users. Signal has indicated that public support for iOS and desktop clients is planned for the near future. Looking ahead, the company intends to allow users to store their secure backup archives in a location of their own choosing, offering even greater flexibility and control over their data. This development is a significant step for Signal, balancing the need for sustainable operations with its core mission of providing secure and private communication.
