    Kostas, Unique Login only ensures that an already authenticated user cannot authenticate again on other computer. Therefore, the login methods you use currently must be active as before. You only need to activate the Unique Login plugin and ensure it is the first plugin on the authentication plugin list to prevent several logins from the same user.

    Thank you Antonio for your answer. Unfortunately no way I can get it to work. The plugin is activated, it is the first in the list of the authentication methods, server sessions are stored in the database etc. etc.
    If you come up with any idea or solution please let me know.

    What do you mean by "When i check unique login as the login method "? Don't set the Unique Login as the authentication method for any user. If this method is active and is the first on the authentication methods list, it will be applied to all users, whatever their authentication method is.

    thank you Antonio. So silly of me. I was selecting as authentication method the Unique Login. I reverted back to manual login (having unique login installed) and everything works fine.
    Thank you for your help and concern!

    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.
