I meant "password protected" as in a "401 status code" response but would be interested in knowing the answers for both...
as far as i know google does not index any 4xx status code responses.
these are reported in GWT as "URL Errors".
you can see these, grouped with any 401, 403 and 407 responses by going to "Health"/"Crawl Errors"/Access denied".
as far as redirecting to a login page, that depends on what status code is used for the redirect.
