WhatsApp upgrades its two-step verification, letting users replace the six-digit PIN with a longer alphanumeric password, and adds support for multiple passkeys (Aisha Malik/TechCrunch)

WhatsApp is enhancing its authentication security by replacing limited six-digit PINs with longer alphanumeric passwords and enabling multiple passkey support, significantly reducing account compromise risks for enterprise users. This upgrade aligns with modern zero-trust security frameworks and passwordless authentication trends, requiring IT organizations to update security policies and user training programs to accommodate the new verification methods. For CIOs managing enterprise messaging security, this represents an opportunity to strengthen endpoint protection while reducing password-related help desk burden through passkey-based authentication.
