A very popular and nifty plugin that prevents duplicate or multiple concurrent log-ins by the same user credentials, for both front-end and back-end. A wonderful and effective tool for websites that share or exchange potentially sensitive information with registered users.
Compatible with Joomla! 3.10.6 and PHP 5.3 or later, PHP 7 and PHP 8.
User must either sign off the first session, or wait until the first session has expired. Super administrators can always have multiple log-ins.
Installation is so simple: just install the package at the Joomla! back-end. See instructions in the downloaded package.
This freeware Trial version is very basic and for evaluation only. The Premium and Business editions are the 'real thing', with full front-end language support and additional options to allow multiple concurrent log-ins for specified groups and users. The Premium Edition is competitively priced and already miles more complete than the freeware version, but if you are running a professional website, you will never regret your purchase of the Business Edition.
The download link also provides access to the J2.5 version.
