One-time encrypted link ready
Share this complete link. The password is encrypted in your browser; the decryption key remains in the URL fragment. The stored ciphertext is scheduled to expire after one retrieval.
⚠This link works once only — after the recipient views it, the password is permanently destroyed.

How it works
01 · Generate
Cryptographically random
Passwords are generated using the browser's built-in crypto.getRandomValues() API — the same entropy source used in encryption. Never Math.random().
02 · Copy or share
Share without exposing it
Clicking “Share via Burn Note” encrypts the selected password in your browser and uploads only ciphertext. The complete link includes the decryption key after the # symbol.
03 · Nothing stored
Zero server involvement
Password generation happens entirely in your browser. Nothing is transmitted unless you choose “Share via Burn Note”; in that case, only client-side encrypted ciphertext is uploaded.
