You’ll soon be able to use Passkey on your iPhone when accessing Meta’s WhatsApp application. That’s according to a code recently discovered in the latest version of the app by leaker and software researcher @aaronp613.

In the screenshots shared by the account on Twitter, the code directly reveals the implementation of Passkey in the app, allowing iPhone users to use their current iPhone authentication details to access WhatsApp.

“Create a Passkey for easier, safer sign in,” the code reads. “With a Passkey, you can use Face ID, Touch ID, or your device passcode to sign in to WhatsApp. Your Passkeys are saved in iCloud Keychain.”

The news follows the rollout of Passkey support for WhatsApp for Android this month, so iOS users will likely have access to it in the coming weeks.

WhatsApp is one of the latest applications to adopt Passkey. In July, TikTok started implementing Passkey to iOS users in Asia, Africa, Australia, and South America. Though the rollout was limited, the company expressed its intention to expand the availability to other regions and operating systems in the future.

Amazon also recently updated its iOS app to support Passkey, saying it would deliver the same support to the Android Amazon Shopping app “soon.” The e-commerce giant said this is part of the evolving authentication environment of the web.

“This is about giving customers ease-of-use and security simultaneously in their Amazon experience,” said Dave Treadwell, senior vice president of ecommerce at Amazon. “While passwords will still be around in the foreseeable future, this is an exciting step in the right direction. We are thrilled to be an early adopter of this new authentication method, helping to realize our vision for a more secure, passwordless internet.”
