Yes, it is possible to disable concurrent logins using the same credentials. To disable multiple logins, follow the steps below:
- Login to Backendless console, select an app and click the Users icon.
- Click the Login menu.
- Make sure the Enable Multiple Logins toggle is set to OFF.
- Once disabled, you will need to determine what happens when someone tried to login with credentials of a user which is already logged in. There are two options: logout first user and logout second user. The first option logs out the user that was already logged in. The second option logs out the more recently logged in user and keeps the other (the one that logged in to the system before the second one) in the system.
