WhatsApp replaces two-step verification six-digit PIN with alphanumeric password and adds multiple passkey support

WhatsApp now allows users to set a longer alphanumeric password instead of a six-digit PIN for two-step verification and supports multiple passkeys for account access
This change strengthens account security by reducing brute-force risks associated with short numeric PINs. For engineers, it signals a shift toward more flexible authentication methods in consumer apps, though adoption may require backend adjustments for passkey management.
