With Shield v6.6+, when you go Pro, you wont ever need a license key. That means you don't have to worry about upgrading 1 site, then upgrading another, and being left with a stack of different keys to sort out.

We've given this innovation an obvious name: Keyless Activation.


You simply:

  1. Log into your One Dollar Plugin account here:

    https://onedollarplugin.com/account/

  2. Then from the top-menu on the page select Keyless Activation
    or go here: https://onedollarplugin.com/account/keyless-activation/
  3. Add the URL of your WordPress site to your account.
  4. Log into your site and select Shield Pro tab
  5. Hit the "Check License" button

Pro features will be automatically licensed on the site within 30 seconds.


Please note that licenses may only be checked once in every 20 seconds. Checks more frequent than this will automatically be skipped.


If you have any trouble with activation, just click a little "Debug" link beneath the "Check License" button (see the screenshot below) and send us an error you see. 

In case you get this error,

stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:\nerror:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure\nstream_socket_client(): Failed to enable crypto\nstream_socket_client(): unable to connect to ssl://onedollarplugin.com:443 (Unknown error)

please contact your web host and let them know of it. The problem is that your PHP installation is not up-to-date and cannot initiate outgoing SSL connection to our site.


Our site does not support the insecure SSLv3 and your site is trying to use this. Only your host can resolve this error.
