Identity & Authentication Market: WhatsApp strengthens account security with passkeys
Meta announced expanded WhatsApp account-security updates that add multiple passkeys per account, replace six-digit two-step verification PINs with longer alphanumeric passwords that allow letters, numbers and special characters, and provide richer incoming-call context (caller country/origin, WhatsApp nickname and whether you share a group), initially on Android. Passkeys enable biometric sign-in via Face ID or fingerprint and build on passkey support introduced in 2024; over one billion accounts have already added a passkey. WhatsApp says its end-to-end encryption protects more than three billion users. The features, described in a WhatsApp blog post and rolling out gradually alongside other changes (usernames and a paid “WhatsApp Plus” tier), aim to reduce phishing and account takeovers and align WhatsApp’s authentication with peers such as Signal and Telegram.
