Calvaweb

Select one or more user accounts that can login to the site using just their password via a custom login form supplied with the plugin. For security purposes, only user accounts with subscriber role can be selected and any accounts selected will be prevented from accessing the wordpress backend. The custom login/logout form is added to a template file using a PHP function ‘pol_showform()’. Like with the standard login form, if you pass ‘redirect_to’ on the querystring, it will use this as the url to redirect to after the login/logout.
<h3>Arbitrary section 1</h3>

Password only login

Log into the site using just your password. Restricted to specific users selected via the wordpress backend.

Little Package

PDF Ink Lite can add a watermark to every page of your sold PDF file(s). It can also password and permissions protect your PDF file(s). The watermark is customizable with font face, font color, font size, vertical placement, and text.
PDF Ink Lite watermarks PDF products when downloaded using WooCommerce download links, and works similarly for Download Monitor and Easy Digital Downloads.
Since the watermark is added when the download button is clicked (either on the customer’s order confirmation page or email, or account page), the watermark can include customer-specific data such as the customer’s first name, last name, and email.
Upon purchase download link, this plugin uses the open source TCPDI and TCPDF libraries to parse and customize your PDF. This process isn’t fool-proof, but works well in many cases. You may encounter problems if your PDF is malformed (bad PDF syntax), encrypted, web-optimized, linearized, or if your server cannot handle the memory load of PDF processing/encryption.
(FYI – This plugin used to be called WaterWoo. Little Package chose to rename it after maintaining it for over ten years.)
