Hi Zeng,

If the external site is just another web application on a different
domain, then this is probably not possible. At least, not possible to
do in a secure way.

If they share a domain, and mediawiki can read (and verify, and use)
the other website's cookies, then you could write your own extension
for it in php, using the AuthPlugin framework. I haven't seen any
examples that did this well, so I think it would be fragile at best.

If the external application is running on your own server, and uses a
directory or it's own database for users, you could use the LDAP
Authentication extension, or do something similar to check the other
application's DB for authentication.

I think those are your options.
