Meta today announced a set of new security features for WhatsApp, including expanded passkey support and stronger two-step verification. WhatsApp now supports more than one passkey for the same account, a welcome feature for users who use both iOS and Android devices. WhatsApp says more than 1 billion people now use passkeys to log back into their accounts with Face ID, Touch ID, or a screen lock code.

The company first introduced passkey support on Android in October 2023 and expanded it to iPhone the following April. Additionally, WhatsApp announced today that its two-step verification feature is expanding beyond a six-digit PIN to support full alphanumeric passwords, including special characters. Finally, this last feature is only available on Android for now, WhatsApp is adding a feature designed to make calls from unknown contacts safer to pick up.

On Android, you’ll now see more information about a non-contact caller, like whether the number is from a different country and if you have any groups in common.
