I want to block so he can’t use the same login on multiple machines.

So I need to know if he’s online, how do I do it on Asp.net identitty?

  • Out of curiosity, what is the purpose of denying the login? Would it be a kind of license control? or security?

  • Jose license control, for example. What prevents a company from hiring your software for 1 user, and use in all sectors? rsrs

  • Got it. For this you will have to create a slightly more complex access control, working together with Asp.Net Identity. I have some suggestions, maybe I’ll draft a response with a possible solution, when I have time left.

  • Jone, I’ve been looking to use Signalr, so I leave a list of logged-in users in memory, something like that...

  • It’s an excellent option. I’ve done something similar to using Signalr in an application.

http connections don’t stay open. This way, you don’t know if a user is logged in or not.

The most common solution for this type of problem would be the Heartbeat standard. You make a javascript that, from time to time (with setInterval), sends an ajax request to the server to inform that the user is still browsing in your application.
