OPKSSH, an SSH integration that uses OpenID Connect to replace long-lived SSH keys with ephemeral ones, has been open-sourced under the OpenPubkey project after Cloudflare gifted the code.
For engineers, OPKSSH removes the burden of managing long-lived SSH keys and their associated security risks, replacing them with ephemeral keys tied to an identity provider. This simplifies access control and reduces the attack surface from compromised or forgotten keys. It also allows SSH from any machine with opkssh installed without copying private keys.

Cloudflare gifted the OPKSSH code to the OpenPubkey project, making it open source.
OPKSSH uses OpenID Connect to generate ephemeral SSH keys that expire by default every 24 hours.
OPKSSH requires no changes to the SSH protocol and adds no trusted party beyond the identity provider.
