Hopefully that's a joke. In case it's not obvious, doing this would
be the equivalent of giving out the password to the account in question.

There's a good chance ssh-keygen really is on the client (it's required
to generate the host keys if sshd is installed) but you can generate
keys on the server and copy them:

[Server]
$ ssh-keygen -t rsa -f $HOME/.ssh/tmp_rsa
(Enter pass phrase)
$ cat $HOME/.ssh/tmp_rsa.pub >>$HOME/.ssh/authorized_keys
(if you want to allow the new key to access the server)

[Client]
$ scp server:.ssh/tmp_rsa $HOME/.ssh/id_rsa
$ scp server:.ssh/tmp_rsa.pub $HOME/.ssh/id_rsa.pub

Once you've tested it, delete the tmp files from the server.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
