Depends what you mean by "secure". Typical use with ssh is to set
CVSROOT=:ext:[EMAIL PROTECTED]:/path/to/cvs/repo
CVS_RSH=ssh
in which case the user will need an account on your machine. If you set
up public/private key pairs then cvs access from the command line is
seamless without requiring "cvs login" (you use ssh-agent to keep your
passphrases for you).
You can "force" a command line by configuring the user's
.ssh/authorized_keys file; you might want to consider setting up a
jailed environment for your users with sshd and cvs in it.
Even after all that, cvs still has enough mechanisms to permit the
execution of arbitrary programs on the server with the user's
credentials; so your cvs server still effectively has a high level of
trust in your users.
If you want something "secure" like this you might want to consider an
alternative source control system. Or maybe, if licensing permits,
offload that risk to sourceforge, who've got a lot of practice at this
sort of thing.
