WhatsApp has introduced passkey-encrypted backups, adding a new security option for users who store chat data on Google Drive or iCloud. The update builds on the platform’s existing end-to-end encryption system, which already protects messages, media, and calls between users.
Passkey protection for chat backups
WhatsApp users often store photos, voice notes, and conversations in backups to preserve memories and important information. To protect this data during device loss or transfer, WhatsApp — the first private messaging app to offer end-to-end encryption for chat backups — is now expanding protection with passkeys.
Key features
- Biometric encryption: Secure backups using fingerprint, face ID, or screen lock.
- No password or long key required: Removes the need to remember or manage a 64-digit encryption key.
- End-to-end security: Backups remain encrypted and private, accessible only to the user.
- Applies across storage platforms: Works for backups stored on Google Drive and iCloud.
- Same protection as chats and calls: Uses the same encryption system applied to messages and calls.
End-to-end encryption background
The company stated that end-to-end encryption, introduced five years ago, now safeguards over 100 billion messages daily for more than 2 billion users. It explained that while chats are stored on users’ devices, many also back them up online, and the encrypted backup system ensures that neither WhatsApp nor cloud service providers can access or read this data.
Availability
The passkey-encrypted backup feature will be rolled out gradually to WhatsApp users worldwide over the coming weeks and months, requiring the latest app version.
