We have released the FREE version of Password Sentry. The FREE version has most of the features and functionality of the PAID version with the following exceptions:
No AuthForm (AF) plugin.
No InterLinking (IL) plugin.
No BandwidthMonitor (BM) plugin.
No user suspensions, but you are alerted (email and/or text message) when password sharing is detected.
The FREE version allows people to try out our app on their server to get a feel of how Password Sentry works. If and when you wish to upgrade to the PAID version, it's just a matter of purchasing a PS license, and then upgrading via the web-based PS AdminCP to convert from the FREE version to the PAID version.
Note that you are installing PS version 8 (PS8). PS8 is Beta, but very close to release as the stable version. PS8 has been extensively tested by our development team, and has been installed and tested on dozens of client servers. No serious issues reported, and any bugs have been resolved. We recommend PS8 to all our clients.
