WhatsApp adds passkey support to encrypted chat backups for improved data security

WhatsApp is enhancing the security of user chat backups by introducing passkey-encrypted backups. Instead of relying on passwords or lengthy encryption keys, passkeys allow users to secure their backup data using their fingerprint, facial recognition, or device screen lock code. This streamlines the backup protection process and removes the need to remember complex credentials.

Following this change, the same security mechanisms that protect personal chats and calls now apply to chat backups as well. Users can access their protected backups conveniently with just a tap or glance, ensuring that their messages remain both private and accessible.

This feature is being rolled out to all WhatsApp users over the coming weeks and months. The gradual launch aims to make enhanced backup security widely available without significant disruptions.
