Hi Everyone,

Is there any feature to prevent multiple login sessions for the same user in Horizon?

That feature could be used to block a second login attempt for the same user when another session already exists or invalidate the the first session right after a second session is opened by the user.

Any reference documentation would be very helpful.

Kind regards, rsoaress
