Random Password Generator

About This Tool

Why use a random password generator?

Weak and reused passwords are the leading cause of account compromises. A strong password should be long, random, and unique to each account. Our generator creates passwords with guaranteed character diversity — at least one character from every selected set — then shuffles them to eliminate predictable patterns.

You control every aspect: length from 4 to 64 characters, and exactly which character sets to include. Whether you need a simple PIN, a memorable medium-strength password (letters + numbers), or a maximum-entropy string with all character types, you can configure it in seconds.

Generated passwords never leave your browser. There is no server, no database, and no log. Your password is produced locally by JavaScript and disappears the moment you close the tab.

How To Use

Start in seconds

// no signup, no install — just configure and generate.

Set Password Length

Drag the slider to choose a length between 4 and 64 characters. Longer passwords are exponentially harder to crack — 16+ characters is recommended.

Choose Character Sets

Select which types of characters to include: uppercase (A-Z), lowercase (a-z), digits (0-9), and/or symbols (!@#$...). More sets = stronger password.

Generate

Click Generate Password (or press Enter). The tool guarantees at least one character from each selected set, then shuffles the result.

Copy & Use

Click Copy to send the password to your clipboard. Paste it directly into your password manager or account form.

FAQ

Frequently asked questions

The generator uses Math.random() which is statistically uniform and suitable for most real-world password uses. For maximum cryptographic security in production systems, use a CSPRNG. For personal accounts, 16+ characters with mixed sets provides excellent protection.

No. Passwords are generated entirely in your browser and never transmitted, logged, or stored. Closing the tab destroys them permanently.

Security experts recommend at least 12 characters for most accounts, and 16-20 for sensitive ones. Longer passwords are always better — use 64 characters for maximum vault-style security.

Including symbols dramatically increases the character space: a 16-character password using only lowercase has ~43 trillion combinations, while one with all four sets has over 1 septillion.

The single-panel tool generates one password per click. Click the button repeatedly to get multiple options and choose your favorite.
