WhatsApp introduces passkeys for encrypted backups — easier, biometric restores

WhatsApp is rolling out passkeys for encrypted chat backups, making it simpler to secure and restore your saved messages, photos and voice notes. Passkeys let you use device biometrics (Face ID, fingerprint) or — on some devices — your screen‑lock code to access backups instead of a separate password or recovery key.

The feature builds on WhatsApp’s end‑to‑end encrypted backup support, which launched in 2021, but aims to remove friction by eliminating the need to remember or store an extra encryption key. WhatsApp says the rollout begins today and will reach users globally over the coming weeks.

How passkeys work

• Authentication: Use built‑in biometrics or compatible device screen‑lock codes to unlock encrypted backups during restores.
• No extra password: Passkeys remove the need to maintain a separate backup password or recovery key.
• Compatibility: Behavior can vary by device and OS — some phones accept screen‑lock codes as an alternative to biometrics.

How to enable (when available)

• Open WhatsApp and go to Settings.
• Navigate to Chats > Chat backup (or Account > Security on some devices).
• If passkeys are available for your account, follow the prompts to register a passkey using your device biometrics or screen‑lock.

Why this matters

Passkeys aim to make secure backups more usable — reducing the chance users skip encryption because of cumbersome recovery keys. They also leverage device‑level authentication, which is generally more resistant to phishing than traditional passwords.

Discussion: Will you enable passkeys for your WhatsApp backups as soon as they appear for you, or do you prefer keeping a manual recovery key? What would make you feel confident using passkeys (multi‑device support, recovery options, or device security guarantees)?
