Yes, on any point to point circuit, which Multinet is.  That is implemented at the routing layer; the password exchange is done as part of the routing layer initialization exchange (Routing Init and Routing Verify messages).  See the routing architecture spec.

Note that this is a plain text password, so all the usual security limitations of plaintext passwords apply.  Also, the way it is set as the circuit attribute is not specified in the standard -- a strange omission because the feature itself IS standardized at the protocol level.
