Password Generator
Generate strong, cryptographically secure passwords and passphrases with custom character sets, entropy calculation, and bulk export.
How to Use Password Generator
- Configure Password Length: Drag the length slider between 6 and 64 characters (16+ characters recommended for high security).
- Select Character Sets: Toggle Uppercase (A-Z), Lowercase (a-z), Numbers (0-9), Symbols (!@#$%), or exclude ambiguous characters (0, O, l, 1, I).
- Inspect Entropy Score: Review the real-time strength meter and bit-entropy calculations.
- Copy or Generate Bulk: Click 'Copy Password' or generate up to 50 passwords at once for team credential setups.
Frequently Asked Questions
Are these generated passwords cryptographically secure?
Yes! Randomness is generated exclusively via the browser's native window.crypto.getRandomValues() CSPRNG engine, backed by your operating system's hardware entropy pool.
Are my generated passwords stored, saved, or logged?
Never. Passwords exist only in your browser's ephemeral RAM and are never transmitted over the internet or logged anywhere.
What is password entropy and why does it matter?
Entropy measures password unpredictability in bits. Passwords with 80+ bits of entropy are virtually impossible to crack with modern brute-force GPU attacks.
What is the 'Exclude Ambiguous' setting?
It removes visually similar characters like '0' and 'O', or '1', 'l', and 'I' to prevent typing confusion when passwords must be entered manually.
Can I generate multiple passwords at once?
Yes! Use the Bulk Password Generation panel to create up to 50 independent secure passwords with one click.
