Housea leading provider of Bitcoin self-custody services, has announced an integration with YubiKeys, allowing users to Bitcoin Vaults with Yubikeys.
YubiKeys are small physical devices that provide multi-factor authentication and securely store sensitive data like passwords and keys. By integrating support for YubiKeys, Casa members can now use the devices as one of the keys in their multi-signature Bitcoin vaults.
When setting up a YubiKey with Casa, users generate a Bitcoin seed phrase locally on their computer. This seed is then stored on the YubiKey itself, protected by a passkey.
The integration uses password cryptography to ensure that seed sentence never leaves the YubiKey and can only be used when authenticating through Casa’s service.
Casa points out that this offers superior security over traditional wallet recovery seeds, which can be vulnerable to phishing and theft if written down or stored digitally. With a YubiKey, the seed is cryptographically tied to Casa’s domain, preventing phishing attacks.
By integrating with YubiKeys, Casa is giving its members more flexibility in securing their Bitcoin. YubiKeys offer convenience through their compact size and simple tap-to-use authentication. The company plans to open source the core integration code of the future.
The launch shows a growing development in Bitcoin self-custody approaches as demand from both private and institutional users increases to make self-custody safer, better and easier.
