About:
OnlyKey Agent acts as middleware that enables a OnlyKey hardware device to function as a smart card for SSH and GPG operations. It facilitates secure key generation, storage, and signing operations directly on the hardware, ensuring private keys never leave the device. This enhances security for developers by providing a physical factor of authentication for encrypted communications.
|
Key Features:
- Hardware-backed SSH and GPG key storage
- Touch button confirmation for signing operations
- FIDO2/U2F support for two-factor authentication
- Cross-platform compatibility
|
Use Cases:
- Securing SSH access to production servers
- Signing Git commits with a hardware token
- Managing multiple cryptographic identities securely
|
Alternatives:
-
YubiKey
– Similar hardware security functionality, but requires proprietary firmware unlike the open-source OnlyKey
-
1Password SSH agent
– Software-based solution that lacks physical hardware confirmation for key usage
