One-Time Secret Sharing for Single-View Handoffs

A one-time secret is a note that should be seen once and then disappear. That is where Burner mode fits: short-lived codes, tokens, or details that do not need to stay open for repeated access. Notes are stored in encrypted form, which makes this a practical workflow for privacy-focused temporary sharing.

This page is the broad guide for any secret meant to be opened once: recovery codes, invite links, temporary passwords, or developer tokens. If your use case is specifically a technical credential handoff, the more targeted guide is API key sharing.

Common situations

  • API keys, access tokens, and reset codes that only need one read.
  • Temporary login information that will be changed right away.
  • Gift card or giveaway links where the first person to open the note should get the reward.
  • Shared computer handoffs where you want the note gone after viewing.

What counts as a one-time secret?

The category is intentionally broad. A one-time secret can be a recovery code, a setup link, a first-login password, a reset token, a claim link, or a developer credential. The shared trait is not the exact content. It is the retrieval rule: the note is meant for one clean read and then should no longer remain available. Related examples include gift card and giveaway links, secure password sharing, and burn after reading.

Why the short-code workflow matters

NoTrace.site combines one-time reading with a 5-character code. That makes it practical when you need speed as much as you need control.

When Burner mode is the better fit

Burner mode is usually the right choice when the note contains an API key, a one-time access token, a first-login password, or a first-open reward link that should not stay available after it is claimed.

One-time secret sharing vs API key sharing

API key sharing is the more specialized page for technical secrets such as PATs, webhook secrets, and developer credentials. This page stays broader so it can cover single-view handoffs across product, support, operations, rewards, and personal workflows.

Simple one-time handoff workflow

  1. Create the note: Start on Create and enter the secret.
  2. Choose Burner mode: Use the one-read option when reopening should not be possible.
  3. Share the code or link: Pass it through a trusted channel.
  4. Let it disappear: Once opened, the handoff is complete. For a full walkthrough, see How It Works.

When not to use it

If the recipient may need to re-check the note before the timer ends, a standard note is usually the better fit than Burner mode. If your real need is long-term secret storage, permissions, or audit history, use a dedicated vault or secrets manager instead.

Frequently Asked Questions

What is the best way to share a one-time secret?
The most secure method is using an end-to-end encrypted 'Burner' note. This ensures the secret is only viewed once and leaves no residual data in chat logs or email servers.
Can I send a one-time secret without a link?
Yes. NoTrace generates a 5-character short code. You can read this code over a phone call, text it, or write it down, completely bypassing the need to send a clickable link.
What if someone intercepts the link before my recipient?
If an interceptor opens the link first, the note is destroyed. When your intended recipient tries to open it, they will see it's missing, immediately alerting you that the secret was compromised before it reached them.
