WhatsApp is enhancing user security by introducing alphanumeric passwords for two-step verification, providing caller context for unknown numbers, and expanding passkey support across multiple mobile devices.

Key Points

• Two-step verification now supports longer, alphanumeric passwords with special characters to replace the traditional six-digit PIN.
• Android users will receive additional context for unknown callers, including country codes and shared group information, to help identify potential scams.
• Over one billion users have adopted passkeys, which utilize biometric authentication like fingerprint or face ID for secure account access.
• Users can now register multiple passkeys to their accounts, facilitating easier access across both Android and iOS devices.

Why it Matters

These updates provide users with more robust tools to defend against account takeovers and unwanted communication. By prioritizing biometric authentication and improved caller transparency, the platform aims to reduce the effectiveness of common phishing and social engineering tactics.
