Share a one time secret
Create a one-time link that self-deletes after being read.
Your secret link is ready
This link can only be opened once. After viewing, the secret is permanently destroyed.
Your Recent Secrets
Passwords, API keys, credentials — shared safely
Stop pasting secrets into Slack, email, or Jira tickets. Oncebin creates encrypted, self-destructing links that vanish after one view.
Paste
Enter sensitive text — passwords, tokens, connection strings, private keys.
Share
Send the one-time link over any channel. The secret stays encrypted.
Gone
One view and it's permanently destroyed. Nothing lingers on our servers.
Encryption happens in your browser. The key lives in the URL fragment and never reaches our servers. Learn more
