WhatsApp rolls out passkeys support for Android devices

Google stated last week that passkeys will be the default authentication option for personal accounts. Google also claimed that passkeys support is expanding, mentioning a number of the companies that have already allowed them on their applications and websites, with WhatsApp mentioned as one of the firms that will be adding compatibility shortly.

This confirms previous claims that WhatsApp has been testing this capability with beta users and that it will be linked to Google's Password Manager. WhatsApp has officially announced that passkeys support is now official for its Android customers, who can now unlock their accounts using their smartphone's screen lock mechanism, such as their face, fingerprint, or device pin.

Previously, WhatsApp offered an optional two-step verification passcode and a fingerprint lock feature that users could configure to activate automatically after a predetermined amount of time. This sort of authentication is not being eliminated from the app, but is being supplemented with passkeys, adding an extra degree of protection.

Although the firm has recently made passkeys support public, it appears that the functionality is not yet available in the app's most recent stable version (v2.23.20.76). It is, however, working in the most recent beta (v2.23.21.12) for individuals who have participated in the WhatsApp beta program.

The enrollment procedure is simple and quick since it uses the screen lock approach that you are already familiar with on your phone. Furthermore, you discover throughout the signup process that your freshly formed passkey is being saved in Google's Password Manager, allowing you to use it on other devices where you are logged in to your Google account. At this moment, it is unclear whether an app update for the stable version of the app is on the way, or if the functionality will be handed out in phases through a server push.

What exactly are passkeys, and how do they differ from passwords?

Passkey is a more secure and convenient method to log into an app or website. Passkeys, as opposed to passwords that you must learn or write down, allow you to utilize your own device's authentication mechanism to accept a login attempt. For example, you can log into Google or WhatsApp using the fingerprint reader on your phone or the fingerprint reader on your Galaxy Book laptop. A passkey contains two keys: one is saved on the app or website, while the other is safely stored on your phone. When you try to log in, the device prompts you to use your smartphone's fingerprint reader to check, and if the data matches, you are logged in.

But what happens if you upgrade to a new smartphone or lose your device? Many services allow you to re-authenticate to a new device using your cell phone number or email address. Alternatively, you may use password managers such as 1Password, Dashlane, and Google Password Manager to preserve passkeys across devices so that if you lose one, you can log in with the other. You may also keep your passkeys on a hardware security key.
