Issue Details

  • I took over a LabVIEW VI that had already been created, but it's password-protected. How can I unlock it? 
  • 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? 

Solution

To unlock a password protected VI you will need to enter the password that was previously set. To unlock a password protected VI you can:
  1. Go to the Protection Properties in a VI, by clicking File>>VI Properties and select Protection under the Category pull-down menu. 
  2. Here, you select Unlocked (no password) to remove the password protection, which will prompt you to enter the current password to successfully remove the password from the VI.

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. 

Additional Information

It's highly recommended to have a system for managing passwords for your VIs.
