Body

I tried:
ssh-keygen -t ed25519-sk -C "myemailaddress@gmail.com"
and:
ssh-keygen -t ecdsa-sk -C "myemailaddress@gmail.com"

but for both commands I receive the following:

Generating public/private ecdsa-sk key pair.
You may need to touch your authenticator to authorize key generation.
No FIDO SecurityKeyProvider specified
Key enrollment failed: invalid format

Any help?

Hello, and thank you for your reply.

I wish what you have provided would help me, but unfortunately, it doesn't.

My hardware is a 1 y/o Mac w/ latest OS, so that shouldn't be the issue.

My SSH Client is up to date, and SSH Config. is good.

In this case the -sk key types explicitly call for the presence of a hardware security key, but it doesn't sounds like you have added one.
Either add a FIDO2-compliant hardware key, or change the type argument to either ecdsa or ed25519 (without the -sk).

Thank you.
