Previously, WhatsApp had implemented an optional two-step verification pin and a fingerprint lock feature that users could set to trigger automatically after a set length of time. This type of authentication is not being removed from the app, but rather joined now by passkeys, offering an additional layer of security.
The signup process is quick and straightforward as it is using the screen lock method that you already use on your phone. Additionally, through this signup process you learn that your newly created passkey is indeed being stored in Google’s Password Manager, which makes it possible to use on other devices where you are signed in to your Google account. It is unclear at this time if an app update is forthcoming for the stable version of the app, or if the feature will be rolled out in stages via a server push.
