Folders: Is it possible toadd passwords to folders?

I'm wondering if there is a way to put a password on a particular folder within my account.  So other people who may use the account can't see the results since there is personal info on the forms we have.

Unfortunately, it's not possible to set up passwords to folders on your account, if you're sharing the folders with sub users, you may select which folders to share so the users do not have access to the other forms/folders. 

Please check this guide that will help you with sub users: https://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-Account-User 

I hope this helps.
