WhatsApp Updates Security Features with Multi-Device Passkey Support and Enhanced Verification

WhatsApp has announced that over one billion users have set up passkeys on the platform, allowing accounts to support multiple passkeys for enhanced security. A passkey enables login via fingerprint, facial recognition, or screen lock code without requiring a PIN. This update addresses user needs for cross-platform compatibility, particularly between Android and iOS devices. The change also involves overhauling WhatsApp’s two-step verification process, transitioning from a six-digit PIN to a longer, alphanumeric password with special characters. Additionally, the company introduced features to combat scam calls by displaying caller details on Android devices. While the billion-user figure reflects passkey adoption rates rather than usage frequency, it highlights ongoing security advancements amid growing concerns about malware exploiting synced credentials and vulnerabilities in mobile authentication systems. The update aligns with broader industry shifts away from SMS-based verification toward more secure passkey solutions.
