The One-Device Rule
Why PastpaperLM ties your account to a device, and what happens if you trigger a violation.
The Rule in One Sentence
One account per device — not "one device per account." You can log into your PastpaperLM account from as many devices as you want (phone, laptop, tablet, school computer). But a single device cannot be used to create or access a second account.
Why This Exists
PastpaperLM is an exam-prep platform with paid features (credits, subscriptions, marketplace unlocks). Without this rule, one person could create unlimited free accounts to bypass daily limits, or share a paid account across many students. The rule keeps things fair for everyone.
How It Works
When you register or log in, PastpaperLM recognizes your device using a technical signature unique to your browser and hardware — not a cookie, so clearing your browser data doesn't reset it.
- If the device is clean (never used for another account), you're fine.
- If it's already yours, you're fine — log in from as many devices as you like.
- If it's already bound to a different account, you'll see a warning — after 3 such attempts, the device is permanently blocked.
What You See If There's a Problem
| Situation | Screen You'll See |
|---|---|
| First mismatch | "Authentication Failed" — with remaining attempts and support contact info. |
| Continued attempts | "Security Notice", then "Final Warning" as you get closer to the limit. |
| Limit reached | "Device Banned" — permanent, only Support can reverse it. |
You cannot "clear" a violation by clearing browser data or using incognito mode. The device signature survives both.
What Counts as a Violation
- Registering a new account on a device that already has an active binding to a different account.
- Logging into a different account on a device bound to another account.
- Using browser automation or multiple profiles to simulate different devices.
What does NOT count:
- Logging into your own account from a brand-new device.
- Using the same account on multiple devices at the same time.
Getting Unbanned
If your device is banned, this can't be undone by you — contact support with your registered email address. Support can lift the ban and give the device a fresh start.
