Question about authentication subkeys and SSH

[James P. Howard, II]

I have created a 2048-bit RSA subkey that is authentication only.  I'd
like to use this with SSH.  A bit of Googling suggests this cannot be
used directly unless it is on a smart card, but it isn't clear.  Have I
correctly interpreted this?

Thank you,
James
