su using ssh

Use ssh-keygen to create privet and public keys for the user say guest.
Now change to root and add a new file in root home directory.
Put public key of guest into it.
Now we can login as root from guest without typing root password.
$ ssh -l root localhost
Make sure ssh service is on.
Pretty handy if you need permission from administrator for each root access.
