Password Generator

Generate cryptographically secure random passwords with custom length and character sets. Includes strength meter and ambiguous character exclusion. Everything runs in your browser — nothing sent to any server. Pro: bulk generate up to 500 passwords.

Frequently Asked Questions

How long should a secure password be?▼

At least 12 characters, ideally 16 or more. Each additional character exponentially increases the number of possible combinations. A 16-character password with mixed case, numbers, and symbols has over 10^30 possible combinations — essentially uncrackable by brute force.

Is this password generator truly random?▼

Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers from your operating system's entropy source. This is the same randomness used in TLS encryption and digital signatures.

Should I use a passphrase instead of a random password?▼

Both are valid. Passphrases (like 'correct-horse-battery-staple') are easier to remember and type. Random passwords (like 'k#9Fm!xQ2pL$') are shorter but harder to remember. Use a password manager either way — the best password is one you don't have to memorize.

What characters should I exclude from passwords?▼

Exclude ambiguous characters (0/O, 1/l/I) when passwords might be read aloud or typed manually. Exclude special characters only if the target system doesn't support them. Otherwise, include all character types for maximum entropy.
