Products that do what Throwaway – single-use, 1-1, e2e encrypted messaging (in-browser) does

Hi HN! Keen to get your thoughts on an encrypted messaging app I've made: throwaway is an in-browser messaging app. It's specifically for single-use, one-to-one, e2e encrypted messaging. This means your messages are encrypted in your browser, and they are only decrypted when they reach your recipients browser. The messages disappear permanently once both browser windows have closed.

Instantly pass your passwords securely▲31
Hey HN! I made a service to share passwords easy and secure but never promoted it. It's called instapass.io I noticed that people besides my friends and clients actually started to use, so maybe it will be helpful for you too! You share one-time self-destruct message using one time links and I won't even be able to see what you wrote. How does it work? When you generate a message the client-side makes a random password and use that to encrypt the message. The password is appended as an anchor tag which all modern browsers never send to the server. This way, I don't even know what you shared.…
