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! 4.2.6 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 and J3.x versions.
