Create a one-time link
A one-time link lets you share a secret once and only once. Whether it is a password, an API key, a private note, or a small file, classified turns it into a single-use link: the content is encrypted in your browser, stored as ciphertext, and the link self-destructs after the first reveal. It is the simplest way to send a 1-time secret without leaving a permanent copy behind.
What a one-time link is good for
Secret share
Share a one-time secret with a teammate or client without copying it into chat history.
Passwords and keys
Hand off a temporary credential or API key that should stop working after it is used once.
Private notes
Send a short, sensitive note that you do not want sitting in an inbox or ticket.
Small files
Share a document or image as a one-time download instead of a permanent attachment.
How the one-time link works
When you create a share, classified encrypts the content locally and gives you a link that points to the encrypted blob. The first time the recipient deliberately reveals it, the stored copy is consumed, so the same link cannot reveal the secret again. Unopened links also expire on the lifetime you choose, so a 1-time secret does not linger if it is never opened.
