Redeem a license key
Paste the key from your email into the loader, HWID binds on first launch, and your dashboard updates within a few seconds.
A Nimbus key looks like nimbus- followed by ~22 alphanumeric characters. It arrives by email from noreply@sellauth.com within 60 seconds of payment confirming (5-15 minutes for crypto, depending on confirmation count). The redeem flow is single-step: paste it into the loader, HWID binds on first launch, you're done.
Two equivalent redeem paths. Either of these works — pick whichever is closer at hand.
Path A: redeem from the loader (recommended). Open nimbus-loader.exe as administrator. The first sign-in screen has a License key field. Paste your key, hit Continue. The loader sends the key to our license server, the server checks it's valid and unbound, and stamps your current PC's HWID against the key. The key turns into a green pill on the loader header and the Launch tab unlocks.
Path B: redeem from the dashboard. Sign into getnimbus.net/dashboard. Open the Keys panel, click Add key, paste the key, hit Save. The dashboard binds the key to your account but does not bind HWID yet — that happens the first time the loader signs in. Next time you launch the loader, the key is already in your account, so you skip the paste step.
What "bound" means. HWID = hardware ID = a one-way hash of your motherboard serial, CPU stepping ID, and primary disk serial. The key remembers this hash. Subsequent launches from the same PC pass instantly; launches from a different PC fail with HWID mismatch until you reset (see HWID mismatch — how to reset).
Pasting tips. The key contains no spaces and no hyphens beyond the nimbus- prefix. If you copied with surrounding whitespace, the loader trims it for you, but the dashboard's Add-key form is stricter — paste cleanly. If your clipboard manager mangled the key, you can find the original in the SellAuth email under "Your Nimbus key".
Multiple keys on one account. Allowed. Day + Week + Lifetime can all coexist; the dashboard shows the longest expiry, and the loader signs in against whichever active key is bound to your current HWID. Buying a second key while one is already active extends your expiry; it does not create a separate slot to share.
"This key is already in use". Means it's bound to a different HWID. If that HWID is yours (old PC), reset it. If you have no idea where it could be bound, the most likely cause is you bought a second key by accident — check your SellAuth order history. If you're sure neither is true, open a ticket — keys do not leak.
