I like to keep a sort of "bridge" table for things like this.

Say, user logs into site A, and their session id -- or some hash of their
personal data -- gets stored in the bridge table with a timestamp (and user
id, or whatever else you want to link up to).

If you drive content from one site to another, you could append their
session id to the URL, and lookup that user on site B, within a given
timeframe (say, 30min since the bridge timestamp was inserted).

If the user/pass info is exactly the same on both sites, you could store a
hash of that in the bridge table (as opposed to the session).

If logins to site B are sensitive, you could include a counter in the bridge
table to only allow one concurrent login.
