The goal of this authentication plug-in is to make sure that each user in Moodle only has one active session simultaneously.

To work properly, the plugin needs that Database-stored sessions are enabled. Have a look at the module documentation on http://docs.moodle.org/20/en/Uniquelogin_authentication to more information.

    Hey!
    It seems this plugin does not support Moodle 3.0?

    I just upgraded to Moodle 3.0 and the plugin gave me this error message: "Coding error detected. This should be fixed by a programmer: session_kill_ user () is removed, use \core\Session\manager :: kill_user_sessions() instead". I was unable to login until I disabled Unique login plugin.

    Is there something i missed or should I just wait for a new version?

    Thanks! smile

    Module works on different laptops and logs out one laptop. Module does not work on 2 browsers on the same laptop. Does not work on smartphones, ie. a desktop and 2 smartphones can login with same user id at the same time. 2 smartphones can login at the same time with the same user id.

    Hi Katja Laakso and Chema Alonso, we launched a new version that is compatible with the version 3.0.
    Hi Rekha C. what type of user are you using? Teacher or Student? Did you see all steps in the installation (https://docs.moodle.org/20/en/Uniquelogin_authentication)?

    Last version works fine here with Moodle 3.0.2+. Thanks for the upgrade smile

    I see that the plugin messages are available only in English and Portuguese. I case you are interested in adding it to the plugin, I've placed a translation to Spanish here:

    By the way, looking at the original file in english I see a message "Aplicar Teacher'. Shouldn't it be changed to 'Apply Teacher'

    Thanks again.

    Hi, I can a see a setting in Moodle -"Limit concurrent logins", using which I can limit concurrent logins. what is the difference in using this plugin?

    This plugin is older than that setting. It is a recent setting (2.9). However, it has some differences, namely, when the limit is reached, Moodle kills the older sessions while the plugin does not allow for a new login. The plugin is also general, it may be combined with other auth plugins while that setting does not work with Single sign on plugins.

    Hi Antonio, please provide for 3.2 version. Missed your reply on 13 jan - i am on 2.9.3 looking to upgrade to 3.2. I require that more than one smartphones must not be able to access a login on custom mobile app, in addition to now allowing login on the desktop site via browsers. Now, with one login, on the custom app, 2 people can use the same login.

    Hi Rekha C we have successfully tested the version 2011051000 in Moodle 3.2.
    Mobile App uses autentication by token therefore the plugin will not work. Because when user signing into the APP with other phone will get the same token.

    Hi Milciades Ramirez. You can activate the module for Administrators and teachers. For students it is always activated.

    Hi António, In a post above you wrote that the Unique Login plugin "does not allow for a new login", whereas the Moodle core setting "Limit concurrent logins" only kills the older session. I can't see that Unique Login does something else.
