how can i put password on unlock

[Claudio_Argentina]

Hi,

you can't add password to "unlock" but you can create a "Locked Project" without the unlock ability.
Open the "Project manager", click on go to the Project menu inside the list. Select "Duplicate".
Check the "Duplicate as locked" option.

I think the password is not necessary

Following  on this topic.  respectfully. 
 In my particular case, it would help me to create the blocked project.  The final client (the one who is going to use the application) does not have access to anything other than the widgets that we give them in the program.  here the connections to devices and also the access to create projects by yourself are vulnerable
