A nifty plug-in that prevents multiple concurrent log-ins by the same user credentials. A wonderful and effective tool for websites that share or exchange potentially sensitive information amongst registered users. Supports Two-Factor Authentication.
User needs to either sign off the first session, or wait until the first session has expired.
Super Users can always have multiple log-ins.

This is a limited Trial edition. It is very basic and for evaluation only. The Premium and Business editions are the 'real thing', with full frontend language support and additional options to allow multiple log-ins for specified groups and users. In the Business Edition, specified users can be denied multiple log-ins and the maximum number of simultaneous log-ins for allowed users can be configured. You can also allow/deny multiple log-ins for any ID/IP combination, and there is much more.

The Business Edition is a 'must' if you are really serious about managing multiple log-ins for your professional website(s).

A log-in gate keeper plug-in that limits the number of log-ins that a user may have within a configured time span. When the time period has expired, the log-in counter is reset. A useful tool for websites that require an additional access control level. This trial edition caters for the front-end only and uses a fixed time span of 15 minutes.

This is a limited Trial edition. The plug-in is also available as a Premium Edition, which includes back-end control and language configuration. It also provides a configurable log-in counter reset time period and allows unlimited log-ins for specified user groups. The Business Edition is the ultimate versatile solution for professional websites and offers additional executive options.

A log-in gate keeper plug-in that progressively delays log-in attempts at the front-end of your website. The progression speed can be configured. Automated brute force log-in attempts are made increasingly inefficient and are eventually given up.

You can use our free Fair Log-in Monitor module alongside this plug-in, as a diagnostic tool that displays the number of back- and front-end log-in attempts that are currently being made. The Monitor can be downloaded free of charge and can help you decide what level of protection your website requires.

This is a limited Trial edition. The plug-in is also available as a Premium and Business edition, for including the back-end function and more.

A plug-in that automatically removes frontend user accounts that have not been activated or used during a configurable period, or have been idle for too long (also configurable). The pruning includes customised user groups.
Specified user accounts can be excluded from being removed.

When the plug-in is fired, is configurable, for example only when a registered user logs in. In this way the server load can be reduced.

This is a limited Trial edition. Also available as a Premium and Business edition, for managing both backend and frontend user accounts, user account management at regular time intervals and more.

A plug-in that continuously monitors your Joomla! install and analyses whether critical user account details have been changed or directories and files have either been modified, added or are not part of a standard Joomla! install. It therefore provides an additional line of defense against website hacking attempts. The plug-in slows down repeated back-end log-in attempts to make brute force attacks frustratingly ineffective.
Optional Remote Monitoring service (see below, 1 week trial for only € 1.25).

The plug-in does NOT prevent hacking attempts and cannot guarantee that your website will never be hacked, but it counteracts certain unusual activities and - most importantly - notifies the site administrator(s) of these activities, thus making sure that hack attempts will not go unnoticed and providing more specific information for the website administrator(s) to remediate these.

This is a limited Trial edition. It has very basic and limited functions and configuration options. If you want the 'real thing', get yourself the Standard or Business edition, with more options and better protection. These editions include, for example, an extended option to autoremove files that are not part of a standard Joomla! install.

About Remote Monitoring:
Remote Monitoring is a service provided by Innato BV and is used in combination with the JHacker Watch plug-in.
Some basic details of your plug-in install will be regularly checked by the monitoring software residing on our server, only to see if these details have changed. No content or other data whatsoever are collected. If the plug-in details deviate from your remote monitoring registration that we have on record, for example when the plug-in has been disabled, you will be notified immediately by email.

A plug-in that automatically disables or removes front-end user accounts of the type 'registered' that have existed for longer than the configured period. In other words: With a configured period of 1 year (example), all front-end user accounts (type 'registered') older than 1 year will be disabled or removed from the Joomla! database, irrespective of whether these users have been active or not.
Whether user accounts are either disabled or removed is configurable.
The plug-in can be used on Joomla! websites that render services to registered users during a limited subscription period.

This is a limited Trial edition.  It only removes front-end user accounts of the standard Joomla! type 'registered' as the only assigned user group, i.e. not authors, publishers, etc., no back-end accounts and no accounts that have been assigned to more than one user group.
Specified front-end user IDs can be excluded from disabling/removal.

Also available as a Premium and Business edition, with more options.

The Business Edition also manages back-end user accounts and it can be extended with a component which allows you to re-activate disabled user accounts.
