Meta Chatbot Told to Hide Data Complaint Options from WhatsApp Users
An investigation by data protection company Redact uncovered hidden AI instructions embedded in about 80 WhatsApp help pages. These instructions, intended for Meta's large language models, included directives not to mention legal documents, liability, or data protection authorities like GDPR when users raised legal issues. The instructions were accidentally exposed in the page code. After Wired contacted Meta, the company removed the leaked instructions, calling them an error. WhatsApp spokesperson Joshua Breckman stated the instructions were meant to ensure accurate and relevant chatbot responses, not to mislead users. Redact criticized the discrepancy between what users are told and what the chatbots are instructed to do, noting that the instructions remained active until mid-October 2026.

WhatsApp testing in-app browser for iOS
WhatsApp is developing an in-app browser for iOS that would allow users to open any link shared in chats directly within the app, instead of being redirected to Safari or Chrome. The feature, discovered by WABetaInfo in the latest iOS beta (26.41.10.72), is still in development and not yet available to testers. Previously, only certain business links with HTTPS were supported. Once activated via chat settings, users can open any website inside WhatsApp, manage cookies and cache locally, and WhatsApp claims it will not have access to links from encrypted chats. The in-app browser session is separate from the chat view, providing a seamless browsing experience. This is part of WhatsApp's broader effort to enhance user convenience. No launch date has been announced.

WhatsApp Deploys Passkeys for 1 Billion Users
WhatsApp adopted passkey-based authentication in 2023, becoming one of the first major consumer apps to do so. The implementation, detailed in an Android Developers Blog post, highlights collaboration with Google to optimize the Credential Manager API and address device-specific challenges. Server-side, WhatsApp uses a Rust WebAuthn library via Erlang, supporting multiple passkeys per account. The transition simplifies sign-in to a single biometric gesture, reduces phishing risks, and improves reliability in regions with inconsistent SMS OTP delivery. WhatsApp is expanding passkeys to in-app re-authentication and working with platform partners to reduce credential creation friction.
- WhatsApp adopted passkeys in 2023 for its billions of users.
- The implementation uses the Android Credential Manager API and server-side WebAuthn/FIDO2.
- Backend is written in Erlang, using the Rust 'webauthn-rs' library for signature verification.
