How Burn-After-Reading Works
The lifecycle of a one-time secret from creation to destruction.
Client-Side Encryption
Your secret is encrypted in your browser using AES-256-GCM. The decryption key exists only in the link URL fragment and is never sent to SecureBin's servers.
Single-View Guarantee
The server enforces one-time access. After the first view, the encrypted blob is permanently deleted. Subsequent requests return a "secret destroyed" message.
Auto-Expiration
Set a custom expiration from 5 minutes to 30 days. Even if nobody opens the link, the data is automatically destroyed when the timer expires.
Create a One-Time Secret in Seconds
No signup. No app to install. Just paste, encrypt, and share.
Type or Paste Your Secret
Enter any sensitive information: passwords, API keys, credentials, private notes, or confidential messages. Toggle "Burn After Reading" for instant destruction upon viewing.
Copy the One-Time Link
SecureBin encrypts your secret in the browser and generates a unique link. The encryption key is in the URL fragment (#), which your browser never sends to any server.
Recipient Views It Once, Then It Is Gone
When the recipient opens the link, the secret is decrypted in their browser and the server permanently deletes the encrypted data. The link is dead. No undo. No recovery.
When to Use One-Time Secret Links
Real-world scenarios where burn-after-reading is the right choice.
Employee Onboarding
Send initial login credentials to new hires. The link expires after their first access, ensuring no one else can use those same credentials from an old email.
Client Credential Handoff
Agencies and freelancers can hand off hosting, CMS, and analytics credentials to clients during project transitions without leaving a trail in email.
Incident Response
Share compromised credentials, forensic findings, or remediation instructions with responders via self-destructing links to avoid creating additional exposure.
