Question : web/url security

There's a long story behind this question, but i'll try to make it as simple as possible... Essentially what I am trying to do is put sensitive files on a webserver for certain people to download (links would be emailed to them) without having them create/remember a username/password.

If i have a file (i.e. PDF file) and I want this to be put on a secure website... is having a random/temporary url path a secure way to do this?

For example if I have a URL such as www.mycompany.com/3kj432df85hjgfi4ufi8gfderii/myfile.pdf

If that path wasn't published anywhere and no direct links were given, are there technologies or crawlers that could find it? Assuming the link would only be valid for a period of 24 hours?

Alternatively are there still ways to embed a username/password in the URL itself? I seem to remember seeing URLs such as http://username:password@somesite.com... is that still done today and cross-browser compatible?

Thanks,
