Share Passwords Securely
Sending a password over chat or email leaves it sitting in plaintext history where anyone with later access can read it. cinderpaste lets you share passwords securely through a single, end-to-end encrypted link that can self-destruct the moment it's read.
Why one-time links beat chat and email
Messages persist. A password pasted into Slack or a mailbox can be searched, forwarded, and exposed in a future breach. A one-time encrypted link removes that trail: once the recipient opens it, the credential is gone from the server for good.
How to share a password with cinderpaste
Paste the password, turn on burn after reading, and optionally add a passphrase the recipient already knows. Send the link over one channel and, if you used a passphrase, share it over another. The paste opens once, then destroys itself.
Best practices
Keep the expiry short, treat the link like the password itself, and rotate the credential after it's been received if it's especially sensitive. Because nothing is stored in plaintext, there's no lingering copy to worry about.
