Password Generator
Create cryptographically secure random passwords with full control over length and character types: uppercase, lowercase, digits, and symbols, with an option to exclude easily confused characters like 0/O and 1/l. Generation uses your browser's crypto.getRandomValues — a cryptographically secure source of randomness — and the password never leaves your device. An entropy meter shows how strong each password actually is.

Frequently asked questions
- How long should a password be?
- At least 16 characters for anything important. Length matters more than complexity: each extra character multiplies the search space, so a long random password beats a short "clever" one.
- Is it safe to generate passwords in a browser?
- This tool uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure randomness source used by security software, and runs entirely offline in your browser — the password is never transmitted or stored.
- What is password entropy?
- Entropy, measured in bits, quantifies how many guesses an attacker would need. Each bit doubles the search space. 60+ bits is decent, 80+ bits is strong, and 100+ bits is excellent for long-term secrets.
- Should I reuse a generated password?
- No — use a unique password per account and store them in a password manager. That way one leaked site can't compromise your other accounts.
