WhatsApp's New Update Lets You Encrypt Chat Backups Using Passkeys

WhatsApp introduces passkey encryption for backups on iOS and Android to replace passwords, enhancing security with biometric or device-based authentication, rolling out gradually worldwide.

  • On Thursday, WhatsApp announced passkey-encrypted backups for iOS and Android, letting users encrypt message history with biometrics or a screen lock code.
  • Previously, backups offered only protection with a password or a 64-digit encryption key, after WhatsApp introduced end-to-end encrypted backups in October 2021.
  • By generating a device-bound key pair, WhatsApp said that passkeys will allow users to encrypt chat backups with fingerprint, face, or screen lock code instead of a cumbersome 64-digit encryption key.
  • WhatsApp says the rollout will add another layer of security for chats, photos and voice notes, gradually reaching users over the coming weeks.
  • WhatsApp's move aligns with growing passkey adoption as Dashlane report found Roblox's passkey logins surged 856%, signaling a shift toward ditching passwords entirely.
