Most people: just sign in
In Folia, open Settings → License and sign in with your Folia account. Your plan unlocks automatically — there’s nothing to copy or paste.

No internet on that computer? Open your dashboard to issue an offline key from the machine code Folia shows under Settings → License, then paste it back there. The key is verified entirely on-device — nothing is sent anywhere.
