What is a one-time link?
A one-time link is a safer way to hand off information that should not remain indefinitely available through ordinary communication channels. You put a password, API key, recovery code, private message, sensitive document, or temporary credential behind an encrypted URL. The recipient opens the link to retrieve and decrypt it in their browser. PrivateNote encrypts the content in your browser before it is uploaded, so the server receives encrypted data rather than plaintext. You choose how long the unused link remains available and how many times it can be opened. That makes a one-time link a secure handoff, not a place to store secrets permanently.

How to share an API key securelyPrivate messages
For information that should not remain indefinitely searchable in email or chat history after it has been read.

For sensitive files where you want encrypted delivery and controlled availability rather than a long-lived shared folder.
Secure file transferWhy use a one-time link?
Sending a password through email, Slack, Teams, SMS, or another messaging service can leave a copy in conversation history, synchronized devices, backups, notifications, and searchable archives. Encryption protects the transfer. Expiration reduces how long the original remains available.
Built for a secure handoff
PrivateNote encrypts messages and files in the browser before they are uploaded. The server receives encrypted data rather than readable content. Decryption happens in the recipient’s browser.
What a one-time link cannot prevent
After opening, an authorized person can still copy, save, or photograph the information. PrivateNote protects the handoff and limits how long the original link stays available. It does not delete copies already saved.
