Web browsers come with features to improve user experience. One of the most popular ones is auto-fill passwords. These are designed for users to store and automatically use their account credentials to access websites and other applications. While auto-fill passwords are convenient, they come with security risks.

Passwords are a double-edged sword. If you make them too simple, they’ll be easy to guess; if you make them too complex, they’ll be impossible to remember. One solution is to create an uncrackable password and save it to your browser. Unfortunately, recent research suggests that tactic could drastically reduce your privacy.
