Samsung Wallet Adds Digital Home Key with Aliro Standard & Matter Support

Samsung Wallet is expanding its capabilities beyond mobile payments and digital IDs with the introduction of Digital Home Key, a new feature allowing compatible Galaxy smartphone users to unlock compatible smart door locks. The rollout, beginning in March 2026, leverages the Aliro standard, a unified protocol designed to streamline access control and address fragmentation in the smart lock market. This move positions Samsung Wallet as a central hub for digital keys, encompassing not only vehicles but now also residential access.

The core of Digital Home Key lies in the Aliro standard, unveiled in late 2023 by the Connectivity Standards Alliance (CSA) – the same organization behind the Matter smart home connectivity protocol. As Neowin reports, the digital key landscape was previously characterized by a lack of interoperability. Users often required separate apps for each smart lock brand – Schlage, Ultraloq, Nuki and others – creating a cumbersome experience. Aliro aims to resolve this by establishing a common communication language between the lock and the mobile device, initially utilizing Bluetooth Low Energy for the initial connection.

How Digital Home Key Works: NFC, UWB, and Matter Integration

Setting up Digital Home Key requires a compatible smart door lock and integration with Samsung’s SmartThings platform, utilizing the Matter standard. Once the lock is connected through SmartThings, users can add a Digital Home Key to their Samsung Wallet during the onboarding process. Access methods vary depending on the smartphone model and the lock’s capabilities. The most common method will likely be near-field communication (NFC), allowing users to unlock the door by simply tapping their phone against the lock. Yet, select Galaxy devices equipped with ultra-wideband (UWB) technology will offer hands-free access through proximity detection, beginning in April 2026. Users can also manage the lock remotely through the Samsung Wallet app.

Samsung emphasizes security, stating the solution is “designed to align with EAL6+ grade certification standards,” providing robust protection against unauthorized access. This certification level signifies a high degree of security evaluation, involving rigorous testing against various attack vectors. According to Samsung, the EAL6+ certification process is expensive and time-consuming, increasing the barrier to entry for manufacturers, but ultimately bolstering security. In the event of a lost or stolen device, users can remotely manage or revoke access through Samsung’s Locate service.

Compatibility and the Expanding Ecosystem

Digital Home Key is currently compatible with smart lock brands including Aqara, Nuki, Schlage, and Xthings (Ultraloq). This initial compatibility represents a significant step towards broader adoption, but the success of Aliro hinges on continued industry support and integration. The Aliro standard’s open nature is intended to encourage wider participation, fostering a more unified and user-friendly smart home experience.

The expansion of Samsung Wallet into home access aligns with a broader trend of consolidating digital credentials into centralized mobile wallets. Beyond payments and boarding passes – with American Airlines being the first US carrier to integrate directly with Samsung Wallet – the platform now encompasses car keys and, with Digital Home Key, access to one’s home. This consolidation offers convenience and potentially enhanced security compared to managing multiple apps and credentials.

Security Considerations and the EAL6+ Standard

Achieving EAL6+ certification is a substantial undertaking. Manufacturers must submit their products for extensive evaluation, including side-channel attacks and other advanced security tests. This process can take months and requires significant financial investment. The high cost reflects the complexity of securing digital keys and the potential consequences of a security breach. While the EAL6+ standard provides a strong baseline, it’s important to remember that no security system is impenetrable. Ongoing vigilance and regular security updates are crucial to mitigating potential vulnerabilities.

What Comes Next: Rollout, Adoption, and the Future of Digital Keys

The initial rollout of Digital Home Key will focus on compatible Samsung Galaxy devices and supported smart lock brands. The pace of adoption will depend on several factors, including consumer demand, the availability of compatible hardware, and the willingness of other smart lock manufacturers to embrace the Aliro standard. Samsung’s success in establishing Digital Home Key as a widely accepted solution will likely influence the future of digital access control. Further development of the Aliro standard, including potential enhancements to security and functionality, is also anticipated. The CSA will continue to refine the protocol based on industry feedback and emerging security threats. Samsung’s announcement signals a move towards a more seamless and secure smart home experience, but the long-term impact will depend on continued collaboration and innovation within the industry.

The broader implications extend beyond convenience. A standardized approach to digital keys could also facilitate new business models and services, such as temporary access grants for guests or service providers. However, it also raises important questions about data privacy and security, requiring careful consideration and robust safeguards to protect user information.
