The goal of this authentication plug-in is to make sure that each user in Moodle only has one active session simultaneously. Once the user logs in, the existing previous session is terminated. Note that this does not work with SingleSignOn plugins.

To work properly, the plugin needs to be on top of the authentication plugins list and Database-stored sessions are enabled. Check the module documentation to more information.

Administrator can configure whether teacher and administrator roles are affected by the plugin.

This plugin is being maintained by ED-ROM, the portuguese Moodle Partner.

I have just installed the Unique login to Moodle 2.5.1 but movement of the Unique login selection to top of the Authentication methods list cannot get the Unique Login to the first line. It only moves as far up to the third place, i.e. below Manual accounts and No login authentication methods.
Therefore It did not work as specified. Any suggestions ?

Similar situation to Collins Ubido
I have just installed the Unique login to Moodle 2.6 but movement of the Unique login selection to top of the Authentication methods list cannot get the Unique Login to the first line. It only moves as far up to the third place, i.e. below Manual accounts and No login authentication methods.
Therefore It did not work as specified. is it because this is only compatible to 2.4? is there a new version coming? Please help!

The plugin can be in third place and still works fine.
We have just tested it with Moodle 2.6.1 (Build: 20140113).
Did you activate the recording of sessions on the database? Please have a look at the documentation:http://docs.moodle.org/20/en/Uniquelogin_authentication#Notes.2FTips

I am looking for a plugin where an user can have only one active session i.e., logged into firefox with one account and then logged into the same account on chrome browser, in such case the user shouldn't be allowed to lo gin in anymore.

Recently, I had installed unique lo gin authentication plugin for moodle2.8+. The installation was good to go without errors. I followed the instructions as given in the plugin documentation.

(1) Enabled session handling

(2) Moved the plugin to the top position in Manage authentication.

But still the user is able to lo gin into fire fox, again in with the same account in chrome. Overall the plugin was not working.

Could you please guide me where I was going wrong..

Many Thanks!!!!

Hi Lavanya Manne. Did you try the plugin with as admin account? Administrators are allowed to have multiple logins.

Hi everyone I can confirm what Lavanya is saying can be replicated in my environment which is moodle2.8 using mysql5 and apache2 on a ubuntu linux installation.
I could not move the uniquelogin plugin at the top in the Manage authentication, I could only get it to the third position as described by others.

I am testing by logging in as a student on my laptop and also on a separate device (tablet)

Any ideas?
How can I confirm that sessions are really being handled by the database as opposed to files?
Is there any debug information I can obtain to figure out what could be causing this?

I tried this on moodle2.8 as well. Doesn't seem to work as the position of the plugin still remains 3rd. I cannot move it any further. any help is much appreciated.

On Moodle 2.8 is no longer possible to move the unique login plugin to the first position. However, this does not compromise the plugin functionallity.
I have just tested it on Moodle 2.8.2+ (Build: 20150123) and the plugin works fine.

You must ensure that the dbsessions option is Administration>Server>Sessions is active.

Hi,
First of all, thanks for this plugin.
Nevertheless I can not have multiple logins with my Administrator account. Is it normal ?
