Unsupported key type sk-ssh-ed25519

Hi, any updates on this?

Hello folks, 

Thank you for the feature request! 1Password currently supports Ed25519 and RSA keys (2048, 3072, and 4096 bits). As Jack mentioned, Ed25519-sk is designed for hardware-backed SSH authentication, where the private key remains on a YubiKey or similar device and each signature may require a touch or PIN.

We’ve filed a feature request to explore storing the key handle and public key in 1Password while delegating signing to the connected hardware key. Even if this feature was implemented, the feature would still require the physical device, and syncing the handle would not back up the hardware-held private key.

For now, generating a new key using a supported type is the best option.
