What is the best strong password generator?

The best strong password generator uses your device’s cryptographic random number generator (not Math.random) and lets you control length and character sets. This free tool does both, entirely in your browser.

How does a random password maker work?

A random password maker picks each character from a pool (lowercase, uppercase, digits, symbols) using crypto.getRandomValues, so every position is unpredictable. Longer passwords from a bigger pool are exponentially harder to guess.

Is this online password generator safe to use?

Yes — the password is generated locally in your browser with the Web Crypto API and is never transmitted or stored. No account, no logs. For safety, store generated passwords in a password manager and never reuse them.

Can I make a safe password without symbols?

Yes — untick symbols and use a longer length (20–32 characters) to compensate. Letters plus digits at 32 characters still offer enormous search space for a safe password tool output.

Q: How long should a secure password be?

Aim for at least 16 characters with mixed character types — this tool allows 8 to 128. Every extra character multiplies the guessing work: a 16-character mixed password is vastly stronger than an 8-character one.

What is Password generator?

Password Generator — Generate strong, random passwords online — choose length and character sets. Free secure password generator, computed in your browser, nothing stored.

A thin adapter around the vendored secure-password-generator engine (mashsys/secure-password-generator, MIT): the engine assembles a character pool (lowercase always, plus uppercase A–Z, digits 0–9, and symbols !@#$%^&*()_+-=[]{};:,.?/ as selected) and draws each character with crypto.getRandomValues. Pure client-side — the password is generated in your browser and never sent anywhere. Honest limitations: selection uses modulo of a 32-bit random value, which carries a tiny statistical bias (upstream algorithm, kept as-is); no strength meter or breach check is included — length and character variety are your guarantees.

How to use Password Generator

1Set the "Password length" (8–128 characters; 16+ recommended).
2Tick "Include uppercase (A-Z)", "Include numbers (0-9)", and "Include symbols (!@#…)" — all on by default for maximum strength.
3Run the tool to generate a cryptographically random password.

Good to know

Generated passwords are random but not checked against breach databases — avoid reusing any password across accounts regardless of strength.
Character selection uses modulo of a 32-bit random value (upstream algorithm) — carries a tiny statistical bias, immaterial for password strength.
This tool provides no strength meter or memorability features; use a password manager to store generated passwords.

Examples

Default 16-character password

Status: ok — a fresh 16-character password drawn from all 86 pool characters.

Long passphrase-style password

Status: ok — 32 characters from letters + digits, easier to type, still very strong.
