To use Krnl, you need to do the key system. This supports the developers of Krnl — it's how they get money. Follow the steps below:
- Join a Roblox game.
- Click on the key system method you want to use (Lootlabs or Linkvertise).
- Click Get Key. It will paste a link to your clipboard.
- Open your browser (Chrome, Safari etc.). Paste the link in the address bar and go to it.
- Wait for the captcha prompt (click the checkbox), then wait for verification. Click Continue and proceed.
- Complete the key system steps (there are two checkpoints on both methods). See details below for Lootlabs and Linkvertise.
Lootlabs
- You’ll see a page with several tasks. Click each task, then return to the page. You do not need to actually complete the external tasks.
- Each task should show a timer that counts down to 0. If a timer doesn’t appear immediately, wait — sometimes tasks finish at different times.
- When all task timers hit 0 they should complete. If they do not, reload the page and try again.
- Click the Unlock Content button, complete the captcha, and repeat to get your key.
Linkvertise
- Click Get Link → then click "I'm interested" → then click Learn More.
- Wait until the task completes — do not click "I ALREADY COMPLETED THIS STEP". This usually takes a minute.
- Click Continue and wait ~10 seconds to access the link. Then click Get Krnl Android Checkpoint.
- Click Open, complete the captcha, and repeat to get your key.
Once you can see your key: copy it, open a Roblox game, and click Verify Key. Keys last 24 hours — if a key doesn't work, generate a new one.
⚠️ KEYS ARE HWID-BASED — only the keys you generate will work for your device. Do not share keys.
Troubleshooting & tips
⚠️ IT IS NOT KRNL'S FAULT IF LOOTLABS/LINKVERTISE IS BROKEN!
- LootLabs: Run the site on desktop mode if you're doing the key on your phone. This will give you one task.
- LootLabs: Some tasks are broken on LootLabs. If you wait more than 120 seconds for a task, reload the page.
- If Lootlabs tasks do not complete/a timer does not show, try installing a VPN (for example: ProtonVPN). Enable it, then reload the key system page.
- If Linkvertise gives a 1-hour restriction, try clearing cookies, enabling a VPN, and reloading the page.
- Open the key link in an incognito window.
- If
krnl.cat
displays an error, restart the key system using the original link you copied.
- If one browser/device doesn't work, try a different browser (Brave, Chrome, Firefox, Safari etc.) or device.
- Use an incognito window.
