Haven’t tried this myself, but you can learn about logging IP addresses in this post:

How do i store a calculated IP in a custom state?

I’ll share how something like this is set up in my apps. First, when a page is loaded, I use the Element Action → Set State workflow and I set a custom state of type text on a floating group (doesn’t have to be a floating group, but this is the only element that exists on every page of this app so it’s a good place to store things like user IP): [image] Then, since I only want to record IP entries from logged in users, I create a new type of thing in my app I call Log_Entry whenever a user i…

Also, you can install ipiphy’s plugin which can help get the user’s IP address.

At the moment, logging a user out and then logging them back in, is a bit of a hack job inside of the Bubble editor. One idea, would be to design your app so that it stores all of your users’ passwords in a separate table/Thing. Then you can have a workflow store their password and email as a custom state…use the workflow to log the user out…then log the user back in using the username and password that you just stored in the custom state. Not ideal from a security perspective, but it should prevent concurrent logins.

How to limit user to login to just one or two devices at a time?

Detect the current user’s device fingerprint Start by detecting the current user’s device fingerprint ID when the page is loaded. Depending on your use case and where the regulation should apply, you may have to introduce it on every page of your app, to do so we use a reusable element that we will add on these p…
