FAQ
Frequently Asked Questions
How secure is this password generator?
This tool uses the browser's built-in crypto.getRandomValues() API, which provides cryptographically secure random numbers. Your generated passwords are never sent to any server — everything runs locally in your browser, so they're as private as possible.
How long should my password be?
Security experts recommend at least 16 characters for important accounts like email and banking. For maximum security, use 20+ characters with a mix of uppercase, lowercase, numbers, and symbols. Short passwords under 8 characters can be cracked in seconds.
What does "no ambiguous characters" mean?
Ambiguous characters like 0 (zero), O (letter O), I (capital i), and l (lowercase L) look similar in many fonts and can cause confusion when reading passwords aloud or entering them manually. Enabling this option removes those characters for clarity.
Can I generate multiple passwords at once?
Yes! Use the Bulk Generate section at the bottom of the tool. Enter a count between 1 and 100, click "Generate All", and all passwords will appear with a "Copy All" option to copy them as a list to your clipboard.
Is my password saved anywhere?
No. Passwords are generated entirely in your browser using JavaScript and are never stored, logged, or transmitted. Once you close the tab, the passwords are gone. We recommend using a trusted password manager to store them securely.
