Binds keys from one certificate to another This command allows one to transfer primary keys and subkeys into an existing certificate. Say you want to transition to a new certificate, but have an authentication subkey on your current certificate. You want to keep the authentication subkey because it allows access to SSH servers and updating their configuration is not feasible.
