Encrypt / One-time secret

One-time secret

Turn a password, key, or note into a link that works exactly once. It's encrypted in your browser; only ciphertext is stored, and the decryption key lives inside the link — in the part your browser never sends to us. When someone opens it, it's read and destroyed.

Anyone with the link can read the secret — so send it through a channel you trust, and let the recipient open it promptly. The link and the secret are the same thing; there's no separate password to remember.
