How to Protect an Article with a Password in Joomla?
Sometimes you have an important page that you don't want every visitor to your site to have access to. The first thing that comes to mind is to make this page accessible only to members, but then you realize that you don't want all your members to have access to this page. Just a few members. So you need an extra level of security on that page. That extra level of security means protecting the site with a "password".
This extension will help you to password protect a Joomla article.
* This extension works for Joomla 3, 4, 5 and 6.
Installation & Usage
1) Login to Joomla Admin > Go to installation page > Install downloaded package.
2) Go to the Manage Plugins section > Content - Article Password > Enable it.

3) Go to Content Management > Select the article you want to protect > Switch to the "Password" tab to set a password. There are 3 parameters:
- Password
- Password hint
- Re-enter the password when: User session expires | Each time
4) Save the post to complete the password setup process.
I migrated about a thousand items with attachments from K2 using your tool and attachments plugin. I initially did this on a test account. Everything worked fine over there. The migrated article attachments worked fine. Then I backed it all up and moved it to my live domain. Now none of the attachments load. All I get is Exception File Not Found and I can't figure out where to look. Turning on error reporting and debug don't tell me anything. I am guessing the old files were not moved during the migration correct? Or how does that all work? I still have all the original folders in the original places as far as I can tell.
