Deploy and Host Onetime Secret - Secure One-Time Message Sharing

Keep passwords and other sensitive information out of your inboxes and chat logs.

About Hosting Onetime Secret

A onetime secret is a link that can be viewed only once. A single-use URL.

When you send people sensitive info like passwords and private links via email or chat, there are copies of that information stored in many places. If you use a Onetime link instead, the information persists for a single viewing which means it can't be read by someone else later. This allows you to send sensitive information in a safe way knowing it's seen by one person only. Think of it like a self-destructing message.
