Detects passwords, tokens and secrets in messaging apps and secures them with end-to-end encrypted SecNote links. How it works? SMP runs silently in the background while you type in your favourite messaging apps. The moment it detects a secret in your message, it replaces it with a short, end-to-end encrypted secure-notes link — so the recipient can open it securely, and it expires automatically. It comes with built-in support for the most popular services and business email.
