Identity · No account required

Start with your npub.
No password. Ever.

Generate a Nostr keypair in your browser. Your private key (nsec) stays local — it's never sent anywhere. Everything in higherMark flows from it.

Step 1 · Generate or import your identity
or import
Identity ready · stored in your browser
npub · public key (share freely)

nsec · private key (never share)
•••••••• · click to reveal
Your nsec is only stored in this browser's localStorage. It is never sent to any server. Back it up before clearing your browser data.
