Free One-Time Secret Link Generator

A one-time secret link is a URL that reveals sensitive content (a password, an API key, a private note) exactly once and then destroys it. After the first successful view, the encrypted payload is gone — there's nothing left on our servers to leak, screenshot from a logging system, or recover from backups.

Type the password into the generator, optionally add a passphrase the recipient must enter, and send the link. The first reveal burns it. If you're worried about the URL leaking — for example into a screenshot, a corporate proxy log, or the wrong Slack channel — the passphrase ensures the secret stays protected even if the URL doesn't.

API keys end up in inboxes, chat history, and screenshots forever when sent in plain text. A one-time secret link removes the key from existence the moment the recipient reads it. Combine it with a passphrase shared over a separate channel for two-factor delivery — the link in email, the passphrase by phone or in person.

OneTimeSecret pioneered the burn-after-read pattern and remains a fine choice if you want a single-purpose open-source tool. LinkPilot is a hosted alternative with a modern UI, optional file attachments on paid tiers, a full audit timeline, and a workspace that also handles your branded short links. The free anonymous tier is comparable: encrypted at rest, optional passphrase, one-time reveal, no account required.

Once you send a password over email or Slack, it lives forever in the recipient's inbox, in backups, and in their search history. Secret links remove the secret as soon as it's been read, so it can't be re-discovered months later by someone else.
