I have a business need case, where when customers phone in, and we want to give them access to common information, like downloads, uploads etc, is there an easier way than needing an email address and password?   What my customer would like to do is give them a code over the phone to access a protected page.

The work around is to create a dummy user which means an email address and a password, and it can't be any of the email addresses that we have already allocated.  

A generic code would be much more convenient.

If we just give them an unprotected hidden webpage, then its possible  others (spammers) could access it as well.  

Sincerely
ray
