WhatsApp introduces three security updates: multiple passkeys per account, alphanumeric two-step verification, and caller details for unknown contacts on Android
These changes reduce account takeover risks and improve call screening for engineers managing team or personal communications. The expanded passkey support simplifies cross-platform logins, while stronger two-step verification adds flexibility. Caller context helps filter potential scams without requiring third-party tools.
