Moodle plugins directory: Unique Login

Hie António Vilela
thank you for your quick response. so in a nutshell it means that this plugin cannot give me what lam looking for, what l want to achieve is prevent multiple login in moodle using the same login details. lam trying to avoid students sharing their login details with their friends because lam running a membership based Learning Management System. l have also tried to use the settings: Admin > Plugins > Authentication > Manage Authentication >limit the number of concurrent logins for a user (l set it to one. and still doesn't work.) Any advice to achieve this functionality would be highly appreciated. Thank you.

I don't know any solution. And if there is one. it has some risks. If there is a problem and the user ends his session without ending the session on the server, he will have to wait the time defined on Moodle settings for the inactive session to be killed, by default 30 mins, before he can login again.
You can think about using Facebook login with a plugin available to this purpose, and prevent other authentication forms. Nobody likes to share his Facebook credentials with friends.

To António Vilela
thank you for your feedback Sir. l was even considering using OAuth_2_authentication, where by students can login using their gmail, facebook accounts. Then it crossed my mind that some students can easily create those accounts only to use it in moodle, hence having no absolute problem in sharing it with their friends. Since those facebook and gmail will only be created to be used in moodle login only. its a very tricky situation. l wonder how others have gone around this especially those who are offering paid membership courses to their students. For now lam stuck, but l will keep on searching hope to get something soon.

If you create the accounts manually using their email, and then users have to login using Facebook, I don't see any problem. Or does Facebook allow the same email on two accounts? I don't think it is possible.

To António Vilela
l think you have a point there and l think thats my best bet. l will definitely work towards that direction. the facebook and gmail login. Ang again, thank you very much for dedicating you time to help me get the solution. Thank you António.

To António Vilela
l would like to thank you for taking your time, all the efforts you made to point me to the right direction. As you have suggested. l have decided to use the OAuth 2 authentication which works like a charm! for those who are interested here is the link: https://docs.moodle.org/36/en/OAuth_2_authentication and here is my login page to my moodle LMS (having incorporated facebook and Google login) https://asifunde.co.za/asifunde/login/index.php

You are welcome. Happy to know you found a solution!

Hello Is this applicable for SSO authentication esp.. SAML?

To arturo guinto
The plug-in will not work because SAML send the user out of moodle to login.
