Chroma-Hash: A Belated Introduction
When you type something into a secure field, each character is displayed as a •. Good news for people who don’t want others to see their password; Bad news for anyone who has a long or difficult password (or is bad at typing). How could we improve the experience of secure text input so that the user entering information could have an idea of what they entered, without anyone else knowing it?
Chroma-Hash approaches this problem using an ambient color representation of the input as it is being typed.
