About this tool

A strong password is your first line of defense. This generator creates cryptographically random passwords using the browser's crypto.getRandomValues() API — the same source of randomness used in cryptographic applications.

Customization options: - Length: 8–128 characters - Uppercase letters (A-Z) - Lowercase letters (a-z) - Numbers (0-9) - Symbols (!@#$%^&*...) - Exclude ambiguous characters (0/O, 1/l/I) — for easier manual typing - Pronounceable passwords — alternating consonants and vowels for memorability

Password Strength Meter — rates your password on entropy bits, estimating crack time with modern hardware. Shows what makes it strong or weak.

Bulk Generator — generate multiple passwords at once for batch provisioning.

Frequently Asked Questions

Is this password generator truly random?
Yes. It uses crypto.getRandomValues() which is cryptographically secure — suitable for security-sensitive applications.
What makes a password strong?
Length is the biggest factor. A 16-character random password is far stronger than a complex 8-character one. Aim for 16+ characters.
What does 'entropy' mean for passwords?
Entropy is the number of bits of randomness. More entropy = harder to guess. A 128-bit entropy password would take longer than the age of the universe to crack.
Should I use a password manager?
Yes. Use a password manager (Bitwarden, 1Password, Dashlane) to store unique passwords. Never reuse passwords across sites.
