Breez SDK Launches Biometric Passkey Feature for Streamlined Bitcoin Custody

In a significant development for bitcoin custody solutions, the Breez Software Development Kit (SDK) has been updated to support biometric passkey authentication, phasing out the need for traditional seed phrase management. On March 18, 2026, Roy Sheinfeld, the CEO of Breez, made the announcement regarding the new Passkey Login feature, which aims to simplify the login process for users by employing biometric verification methods.

The introduction of this feature into the Breez SDK marks a pivotal advancement in enhancing security and user convenience in the cryptocurrency space. By leveraging the WebAuthn Level 3 PRF extension, the system is designed to securely and deterministically generate cryptographic keys. This process ensures that users can easily access their bitcoin holdings without the cumbersome task of remembering and securing a manual seed phrase, thereby significantly reducing the potential for user error and increasing the overall security of bitcoin self-custody.

This update is a testament to Breez's commitment to pushing the boundaries of innovation within the cryptocurrency industry, offering developers the tools to integrate cutting-edge security features into their applications. The move to biometric passkeys not only streamlines the login process but also sets a new standard for access control in digital asset management, making it more accessible and secure for a broader range of users.
