Homea leading provider of bitcoin self-custody services, has announced an integration with YubiKeys, which will allow users to protect their bitcoin vaults with Yubikeys.
YubiKeys are small physical devices that provide multi-factor authentication and securely store sensitive data such as passwords and keys. By integrating support for YubiKeys, Casa members can now use the devices as one of the keys to their multi-signature bitcoin vaults.
When setting up a YubiKey with Casa, users generate a bitcoin seed phrase locally on their computer. This seed phrase is then stored on the YubiKey itself, protected by an access key.
The integration uses passkey cryptography to ensure that the seed phrase never leaves the YubiKey and can only be accessed when authenticated through the Casa service.
Casa emphasizes that this provides superior security to 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 linked to Casa’s domain, preventing phishing attacks.
By integrating with YubiKeys, Casa offers its members more flexibility in protecting their bitcoins. YubiKeys offer convenience thanks to their compact size and simple, one-touch authentication. The company plans to open-source the core integration code in the future.
The launch demonstrates the growing development of bitcoin self-custody approaches as demand grows from retail and institutional users to make self-custody safer, better and easier.
