I think this note explains a lot about CFIDE and CFTOKEN: http://cfmxplus.blogspot.com/2002_06_23_cfmxplus_archive.html
As mentioned in above article, by default CFIDE and CFTOKEN are just pseudo-random numbers that are rather short, thus, there is a chance of them repeating.

CFID and CFTOKEN combination MIGHT be unique, but I have a feeling eventually you will run into dupes there as well... Why not just generate a UUID to store in the database? -----Original Message----- From: Webmaster at FastTrack On Line [mailto:[EMAIL PROTECTED] Sent: Friday, October 07, 2005 9:53 PM To: CF-Talk Subject: CFID Hi all, CFID and how it really works is something I've never got to the bottom of. I have never been able to find docs on MM that really explain it. Scenario - I run a dating site and each time a user registers I store the cfid against their user record in an ms sql table. I'm been told that CFID is a unique ID field and can't ever repeat. However, I have maybe 100 dupe records, those with the same CFID. How can that possible happen? Thanks in advance for any help explaining what's going on.
