FAQ
Is the Password Generator free?
Yes completely free, no account, no daily limit. It runs entirely inside your web browser using Web Crypto.
Are generated passwords stored or transmitted?
No. Passwords are generated locally using the browser's cryptographically secure random number generator (getRandomValues). They are never sent to any server or saved anywhere.
How secure are the generated passwords?
Password strength depends on length and character set. The tool excludes ambiguous look-alike characters (O, 0, I, l) for readability. Estimated strength is shown, but real security also depends on avoiding reuse, phishing, malware, and using a trusted device.
Can I customize the character sets?
Yes. You can include or exclude uppercase (A-Z), lowercase (a-z), numbers (0-9), and symbols. There's also an option to exclude ambiguous characters for easier reading.
