Officially "no" and I don't think I've seen a hack for this before. Once upon a time I created a "guest account" that random visitors could use by guessing the login and password based on clues provided on the login page, but I don't have the hack required anymore.
Do you have direct contact with these potential users? Are they using private computers or shared systems? If you can get with them in person and they're using private computers then walk them through logging in and tell them to not log out.
Alternatively, and again only if you have direct contact, you could suggest they use their first name as login ID and their last name as their password. It's not the safest credentials in the world, but I'm thinking it's not likely they'll forget those to pieces of info.
