What Is the Password Generator?
A strong password is your first line of defense against unauthorized access. Humans are bad at generating truly random strings, unconsciously using patterns, names, and dates that automated attacks can crack in minutes. This tool uses the browser Crypto API to produce cryptographically random passwords. The strength meter evaluates your configuration and gives real-time feedback. No generated passwords are stored or transmitted anywhere.
