Signal President Criticizes OS-Level AI Agents Over Privacy Risks
At the TechBBQ conference in Copenhagen, Signal President Meredith Whittaker warned that upcoming OS-level AI assistants, like Apple's Siri and Google's Gemini, present an existential threat to privacy. These integrated agents bypass end-to-end encryption by capturing screen content, such as screenshots, to process data via external large language models (LLMs). Whittaker linked the current AI boom to the ad-supported, mass-surveillance business models established in the 1990s, arguing that Big Tech's economic structures prevent true privacy. Without platform-level opt-out controls from Apple, Google, or Microsoft, she warned that privacy-focused apps like Signal may struggle to guarantee integrity within one to two years. Whittaker reaffirmed Signal's commitment to user trust, noting that the nonprofit requires approximately $50 million annually to operate, funded entirely by donations to resist commercial revenue and data monetization pressures.

Anthropic Unifies Claude and Cowork Memory
Anthropic announced it has merged the memory systems used by Claude chat and Claude Cowork so information learned in one experience is available in the other. The company now exposes stored memories so users can read, edit, or delete them, and memories are added incrementally during conversations rather than only at the end. By default Claude will exclude certain sensitive categories (health, race, religion, politics, gender identity) unless users opt in via an “include sensitive topics in memory” toggle; it will never save government IDs, Social Security numbers, criminal history, immigration status, or items violating its acceptable use policy. The memory feature is enabled by default across Free, Pro, and Max plans on web, desktop, and mobile (mobile users must update apps).
- Anthropic merged the memory system used by Claude chat and Claude Cowork so memories are shared between the two experiences.
- Users can now read, edit, or delete what Claude has retained in memory.
- Claude adds topics to memory during a conversation (incrementally) rather than summarizing only at conversation end.

WhatsApp strengthens account security with passkeys
Meta announced expanded WhatsApp account-security updates that add multiple passkeys per account, replace six-digit two-step verification PINs with longer alphanumeric passwords that allow letters, numbers and special characters, and provide richer incoming-call context (caller country/origin, WhatsApp nickname and whether you share a group), initially on Android. Passkeys enable biometric sign-in via Face ID or fingerprint and build on passkey support introduced in 2024; over one billion accounts have already added a passkey. WhatsApp says its end-to-end encryption protects more than three billion users. The features, described in a WhatsApp blog post and rolling out gradually alongside other changes (usernames and a paid “WhatsApp Plus” tier), aim to reduce phishing and account takeovers and align WhatsApp’s authentication with peers such as Signal and Telegram.
- WhatsApp is rolling out three security features: multiple passkeys per account; full alphanumeric two-step verification passwords with special characters replacing six-digit PINs; and richer incoming-call context (caller origin, WhatsApp nickname, and shared-group status), initially on Android.
- Passkeys support biometric sign-in (Face ID or fingerprint), build on passkey support introduced in 2024, and can be added to multiple devices/accounts.
- WhatsApp’s end-to-end encryption protects more than three billion users, and over one billion accounts have already added a passkey.

Meta launches WhatsApp Business MCP server for AI agents
Meta has introduced a new Model Context Protocol (MCP) server, the WhatsApp Business Tools MCP, enabling AI coding agents like Claude, Cursor, Codex, and ChatGPT to automate the setup and management of WhatsApp Business messaging. This addresses the previously cumbersome process that required developers to navigate multiple tools. With this MCP server, AI agents can handle tasks such as creating the business account, verifying phone numbers, registering for Cloud API access, and managing messaging templates. They can also test webhooks and monitor compliance-related issues like Terms of Service and payment methods. The initiative is part of Meta's broader expansion of MCP servers, which now also include ones for ad management and app configuration.
- Meta launched the WhatsApp Business Tools MCP server on September 15, 2026.
- The MCP server allows AI agents like Claude, Cursor, Codex, and ChatGPT to manage WhatsApp Business setup.
- AI agents can automate creating the WhatsApp Business account, phone number verification, and Cloud API registration.

WhatsApp Tests Support for Up to Three Accounts on iOS
WhatsApp, a Meta-owned messaging app, is reportedly testing an extension of its multi-account feature for iOS, allowing users to manage up to three accounts on a single device. The feature was spotted in the TestFlight beta version iOS 26.37.10.15, indicating it's currently available only to early testers. This would build upon the existing two-account support and could benefit social media managers and business users by enabling them to handle multiple personal and professional accounts without needing a second device. The report comes from WABetaInfo, a publisher specialized in WhatsApp updates. No official release date has been announced.
- WhatsApp is testing support for up to three accounts on iOS devices.
- The feature was discovered in the TestFlight beta version iOS 26.37.10.15.

WhatsApp Testing Guest Calls, Event Hub, Restricted Chats
WhatsApp is developing three new features: guest calls allowing people without a WhatsApp account to join voice and video calls via browser links, a centralized Event Hub for managing events and sharing invitations with non-users, and Restricted Chat to protect private conversations from access via linked devices and AI agents. The features were discovered by WABetaInfo in beta versions for iOS and Android. Guest calls, currently in development, would let iOS users create call links that guests can open in a browser without installing the app, with end-to-end encryption maintained. The Event Hub, found in Android beta, aggregates event creation, management, and responses, and allows sharing event links with non-WhatsApp users. Restricted Chat, also in Android beta, builds on Advanced Chat Privacy to prevent chat export, automatic media saving, sharing with Meta AI, and access from linked devices. Rollout dates are not yet announced.
- WABetaInfo discovered guest calls in WhatsApp Beta 26.36.10.71 for iOS, allowing people without accounts to join calls via browser links.
- WhatsApp introduced guest calls for iOS, but the feature is still in development and not available to beta testers yet.
- WABetaInfo found the Event Hub in WhatsApp Beta 2.26.36.5 for Android, centralizing event management and allowing sharing event links with non-users.
