Will Rupt block my real customers?

No. Rupt always starts with a conservative approach to minimize false positives. It also always allows real users to verify their ownership via 2FA and move on. Only sharers are challenged.

What happens when Rupt detects account sharing?

You choose. Notify the account owner, ask the extra person to verify with 2FA, or limit the devices. We'll help you pick the right policy that drives revenue and doesn't hurt your real users.

How long does it take to integrate?

Most teams ship in a day. Drop in the SDK for web, iOS or Android, call evaluate, and that's it.

Does it still work if users clear cookies or use a VPN?

Yes. Device identification does not rely on cookies, so clearing them or opening a private window does not reset it. Location signals are corroborated across a device's history rather than trusting a single IP, so a VPN on its own does not create or hide a signal.

Premium starts at $99 a month, which includes credits you spend across evaluations and executed challenges. Most account sharing setups only challenge a small share of sessions.

Account sharing detection and prevention software

The engine

Account sharing prevention like you've never seen before.

Detect account sharing with the highest accuracy, zero false positives, and without annoying your real users.

1Device tracking

Rupt tracks every device that touches the account.

Someone opens your product on a MacBook in Berlin. Rupt identifies the physical device, not just the browser, and ties it to the account from the first page view.

Don't blindly challenge real-world usage.

The same account opens on an iPhone in the same city. A laptop and a phone is how real people use software, so nothing fires. Rupt errs on the side of your customer.

A third simultaneous device trips concurrency and impossible travel.

Rupt is not counting devices. It watches for the things that only make sense if more than one person is involved: three sessions live at once, and a jump between cities no human could make in four minutes.

A fourth device pushes the account past its device limit. Rupt challenges the sessions that do not belong to the owner, and leaves the owner alone.

Your real users

Frictionless experience for legitimate users.

The most common worry about account sharing prevention is that it punishes good customers. Here is what actually reaches them.

The account owner keeps working
The challenge lands on the session that does not belong, not on the person paying the bill. Nobody gets logged out mid-task to prove who they are.
Two devices is not sharing
Nothing fires because someone opened your product on a laptop and a phone. Signals only trip on patterns one person cannot produce, like three live sessions across two cities.
You pick what happens next
Notify, verify by email or one-time code, cap the account to a device limit, or offer the extra person their own subscription. Set it per policy and change it whenever.

Integration

Ridiculously simple to integrate.

Install the SDK, and call a function. Or if you run on a no-code platform, install the snippet and you're done! Everything after that is configurable via AI or policy editor.

import Rupt from "@ruptjs/client";
const rupt = new Rupt({
  clientId: "your_client_id",
  on_logout: () => signOut(),
});
await rupt.evaluate.access({
  user: user.id,
  email: user.email,
  phone: user.phone,
});
