WhatsApp testing alphanumeric passwords for two-step verification

WhatsApp is developing an alphanumeric password to replace the current six-digit two-step verification PIN.

The new password must include both letters and numbers, making it harder to guess than a numeric code.

WhatsApp will check password strength before allowing users to save it.

The password will be required after SMS verification, adding a layer against account takeover attacks like SIM swapping.

The feature is under development in the latest Android beta and not yet available to users.
