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 to be on top of the authentication plugins list and Database-stored sessions are enabled. Check the module documentation to more information.
This plugin is being maintained by ED-ROM, the portuguese Moodle Partner.

You are welcome. Happy to know you found a solution!
The plug-in will not work because SAML send the user out of moodle to login.
Is it not compatible with 3.7?
@Vijaya Kumar Do not set Unique Login as a user authentication method. Please see the correct use in https://docs.moodle.org/20/en/Uniquelogin_authentication
It works fine. I recommend to anybody who uses this plugin that, follow the installation instructions. Moving the plug-in to the top position is very important. Otherwise, it may not work with some of the 2-factors verification plugins.
Thank you, Antonio.
Regards.
When will version 3.9 be out? Any idea? Does version 3.8 work ok with 3.9
Thanks and Merry Xmas.
If a user is already logged in, and tries to login again (on a different browser or device), what happens exactly? Will the second session be refused or will the first session be closed?
I suggest that this is made clearer in the description, if possible.
Thanks.
