There have been extensions that have done this in the past.
The MIT Kerberos distribution used to ship with modified telnet
client and server programs that would do krb auth instead of
manual username/password entry.  Those are long gone, though.
RFC 1409 specifies an authentication extension (likely used by
kerberized telnet, now that I think about it...), and there was
another extension to provide auth via DSA certificates.

None of those are what you're looking for though, I expect.
The BSD telnet client has a `-a` option to negotiating
"autologin"; I suspect it uses something like the BSD rcmd
stuff used by rlogin etc.  It's not clear from looking at
the source code whether it's even still supported in any
meaningful way.

You're probably better off trying to set up rlogin or some
kind of ssh wrapper, instead.
