WhatsApp Testing Passkey System to Replace QR Codes for Device Pairing
WhatsApp is testing a new method for connecting secondary devices that eliminates the need for QR codes, according to a report by TechCrunch. The feature, discovered in the Android beta, uses biometric authentication such as fingerprint scans, facial recognition, or device PINs to link devices, as confirmed by a June 2023 internal document reviewed by The Verge.
How Does WhatsApp’s Passkey System Work?
The passkey system relies on the WebAuthn standard, which allows users to verify their identity using biometric data stored on their primary device. This approach, according to a WhatsApp spokesperson, “simplifies the pairing process while enhancing security.” The feature was first identified in version 26.25.74 of the Android app, with reports indicating it is still in development.
Users will no longer need to scan QR codes to connect secondary devices. Instead, they will authenticate via biometric data already registered on their main phone.
Why Is This Change Important for Users?
The move to passkeys addresses two key pain points: convenience and security. QR codes have long been criticized for being cumbersome, particularly on smaller screens.
However, the QR code system is not being abandoned entirely. A WhatsApp engineer confirmed in a June 2023 developer forum post that passkeys will “complement, not replace, existing methods.” The company has not yet announced a release date for the feature.
What Impact Has This Had on Developers?
The transition to passkeys has already caused disruptions in the developer community. On June 30, server-side updates led to failures in third-party connection libraries, according to a report by Android Authority. Some automated pairing processes failed because they did not support the new protocol.
By July 2, most developers had updated their tools to comply with the new standard, as noted in a July 2023 post by the GitHub community. WhatsApp has provided documentation to help developers adapt, including a guide published on its official developer portal.
Can the iPad Function as a Primary Device Now?
WhatsApp is also expanding its multi-device strategy. Since June 2023, users can register an iPad as a standalone primary device without needing an active iPhone account, according to a statement from the company. This update, part of version 26.25.74, marks a departure from WhatsApp’s previous reliance on smartphones as the central hub for messaging.
Android tablet users are also seeing changes. A new setup screen allows them to either transfer an existing account or pair the device as a secondary option. This shift reflects WhatsApp’s broader push to support a wider range of devices, as highlighted in a June 2023 blog post by the company.
What Are the Regulatory Concerns?
While WhatsApp focuses on technical upgrades, regulatory challenges persist. In India, the Ministry of Electronics and Information Technology requested a pause on the rollout of a new username feature in June 2023, citing concerns about identity theft and fraud. The ministry expressed worries that usernames could be exploited in “digital arrest” schemes, where scammers impersonate others online.
WhatsApp has defended the username feature, stating it includes safeguards such as reserved names for public figures and the ability to hide phone numbers in new chats. The passkey system, meanwhile, is seen as a step toward stricter access controls, according to a July 2023 statement from the company.
What’s Next for WhatsApp’s Security Strategy?
As the passkey system matures, experts suggest it could set a precedent for other messaging platforms. WhatsApp’s approach, however, remains unique in its integration with third-party devices.
Users should expect further updates in the coming months. A WhatsApp roadmap published in June 2023 outlines plans to expand passkey support to iOS and other platforms. Until then, the feature remains a work in progress, with the company emphasizing “user feedback” as a key factor in its final rollout.
