How SecureNote works
SecureNote is for handing someone a password, key, or other short secret without leaving it sitting in a chat thread or an inbox forever. Secrets travel as one-time, expiring links: the first person to open one sees the secret, and at that moment it's gone.
The part that matters: everything is encrypted in your browser before it leaves your machine. Our server only ever stores an unreadable blob — we can't read your secrets, and neither can anyone who only gets at our database.
Creating a link requires an InternalCars sign-in. Opening one never does — recipients and customers need nothing but the link they were given.
