Is My Password Safe?

Is this feature safe?
This feature is implemented entirely in JavaScript, which is a client-side scripting language, meaning all calculations are performed by your computer. This means that once the webpage is fully loaded in the browser, there is no further data that needs to be read from the server, and there is no further connection with the server, let alone obtaining any information from your computer. If you want to confirm this, you can close the network connection after the webpage is loaded, and everything will continue to work:)
