It seems like it's been mentioned on here before, that a number of "two

Anyone here have specific experience with such solutions, or opinions
about how much security they add to a system?


Sounds completely bogus to me.

The cookie is typically generated by the server, as a response to an authentication event (single or multi-factor). The cookie is then used to maintain that authentication from request to request.

There is NO authentication component in such a cookie. It is created by the SERVER, and as such CANNOT qualify as an authentication factor at all.
