A highly addressed concern in previous versions of NX was the security surrounding supplier collaboration. To address this issue, NX 12 now features the ability for a simple part file password. This provides the ability to protect parts with passwords.
Here are some capabilities and restrictions associated with part passwords:
Apply different levels of access to each part file
Password safe to store and apply saved passwords
Customer Default to control site access
Private/Public Key option for recovering passwords at users site
Passwords removed when importing to Teamcenter, admin password required
Translators, command line utilities, and batch mode operations NOT supported
