Hello @marianadalto,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issues you are having with your shared passwords. The lock icon only means that the item is a password, it does not mean that the password is hidden. Please revoke the share from the sharing center and share it again, be sure to not select the option to "Allow Recipient to View Password'.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
