Our VAPT report has logged a low severity issue whereby the web application allows multiple concurrent multiple logins per user.

Can please advise if DNN has a feature to enable / disable multiple concurrent logins per user? If none, is there a way to disable concurrent logins for the same user?

At this time there is not a supported configuration option to only allow a single login, you would need to look at customizations to the platform to support a single-login-session behavior.

I am not aware of any third-party solutions for this at this time.
