Enter the message or password you want to share securely. After you submit the message by pressing the "Create secret" button, you will receive a link. Send this link to your messaging partner so they can read the secret message.
Attention! The message can be read only once! After it's read, the message will be destroyed and cannot be restored. Also note that if you send the link through an application which provides a preview of websites, it may try to download and create a preview for this link as well by fetching the URL. This means that this third-party tool will read and destroy the secret. To prevent this, it's suggested to use the JavaScript-enabled version of the application which can address this issue with some additional mechanisms.
