Issue Details

  • I password protected my LabVIEW VI and now I would like to unlock it, but I can't remember how to do that. How do I unlock my password protected VI? 
  • I took over a VI that had already been created, but it's password-protected. How can I unlock it? 

Solution

To get to the Protection Properties in a VI, select File>>VI Properties and select Protection under the Category pull-down menu. 

Here, you select Unlocked (no password) to remove the password protection. 

Additional Information

In case you are not the developer of this VI, and you do not have the password to unlock your VI, NI provides the following recommendations:
  • Try to contact the developer of the VIs for the password.  
  • Try contacting the developer's manager or other employees that may know the password.
  • Try commonly used, company passwords.
  • In case you are not able to obtain the password, consider rebuilding the code. 
  • It's highly recommended to have a system for managing passwords for your VIs.
