oob / out of band share a secret burn after reading link one time secret link
Share a secret. Once.
Keep credentials out of the Slack thread, the ticket and the email chain. Paste a password, API key or token and get a link that works for a set number of views, then deletes itself permanently. No account, no tracking, nothing left behind.
Additional options
Your link is ready
Send it to one person. We can't recover it once it's gone.
Paste into your own mail client - nothing is sent from here.

Out of band
The secret travels separately.
Sending a credential out of band means moving it off the channel that needs it - not pasted into the thread, the ticket or the inbox, where it sits forever and gets forwarded. OOBSecret is that separate channel: a one-time link that carries the secret and then destroys it.
01
Encrypted on your device
The key lives in the link fragment and never reaches the server. Stored ciphertext is useless without it.
02
Opened by the recipient
They open the link - optionally entering the passphrase you shared separately - and the secret is decrypted locally.
03
Deleted for good
Once the view limit or the clock runs out, the record is purged. Re-opening the link shows nothing.
Why it's safe
Built to leave no trace.
Zero-knowledge by design
Ciphertext goes to the server, the key stays in the URL fragment. We can't read what you shared.
Expires on your terms
Cap it by view count, by clock, or both. Whichever limit is hit first destroys the record.
No account, no log
Nothing to sign up for and no analytics. Rate limiting sees a hashed address, never a stored one, and there is no profile of you to build.
AES-256-GCM, key generated and held in your browser, never transmitted. Read the security model
