Password Generator
Generate strong, random passwords in your browser. Choose length (8-64) and mix uppercase, lowercase, numbers, and symbols. Built on secure crypto randomness - nothing is uploaded or stored.
Choose a length and character types below, then generate.
About Password Generator
Create strong, unpredictable passwords instantly - right in your browser. Set the length from 8 to 64 characters and toggle uppercase letters, lowercase letters, numbers, and symbols to match any site's rules. Every password is built with the browser's cryptographically secure random generator (crypto.getRandomValues), not the predictable Math.random, and is guaranteed to include at least one character from each type you enable. Nothing is sent to a server, logged, or stored, so the password you see is for your eyes only.
How to Use Password Generator
- Choose a length with the slider or number box. Longer is stronger - aim for at least 16 characters where the site allows it.
- Turn on the character types you want: uppercase, lowercase, numbers, and symbols. Using all four gives the strongest result.
- The password is generated automatically. Click Regenerate (or change any option) to roll a fresh one.
- Check the strength meter, then click Copy and paste the password into your sign-up form or password manager.
Password Generator Examples
Strong 16-character password
All four character types at length 16 produces something like g7$Kp2!vQ9zR#mL4 - strong enough for most accounts.
Maximum-security 32-character password
Set length to 32 with every type enabled for banking, email, and password-manager master passwords.
PIN-style numeric code
Enable numbers only and set a short length to generate a random numeric code for offline use.

Frequently Asked Questions about Password Generator
- Are these passwords safe to use?
- Yes. Passwords are generated with crypto.getRandomValues, the browser's cryptographically secure random number generator - the same class of randomness used for security tokens. Generation happens entirely on your device, so the password is never transmitted, logged, or saved anywhere. For maximum safety, generate the password on a trusted device and store it in a password manager.
- How long should my password be?
- Length matters more than anything else. Twelve characters is a reasonable minimum, 16 is a strong default, and 20 or more is ideal for important accounts like email, banking, and your password manager's master password. This tool supports up to 64 characters. When a site allows it, longer always wins.
- Does every password include all the character types I select?
- Yes. If you enable uppercase, lowercase, numbers, and symbols, the generator guarantees at least one character from each of those sets, then fills the rest randomly and shuffles the result. This helps you satisfy sites that require a mix of character types without weakening the randomness.
- Why use a generator instead of making up my own password?
- Humans are predictable. We reuse passwords, base them on names, dates, and dictionary words, and follow patterns that attackers' cracking tools expect. A random generator removes that bias, producing passwords with far higher entropy that are much harder to guess or brute-force.
- Is this password generator truly random?
- It uses the Web Crypto API (crypto.getRandomValues) with rejection sampling to avoid bias, which is cryptographically secure - unlike Math.random, which is predictable and unsuitable for security. Each character is chosen independently, so results are not weighted toward any pattern.
- Do you store or send the passwords anywhere?
- No. Everything runs client-side in your browser. The password is created locally and never leaves your device - there are no uploads, no accounts, and no server logs. Refreshing the page discards it, so copy it somewhere safe before you navigate away.
- Should I exclude symbols?
- Only if a site rejects them. Symbols increase the size of the character pool and make passwords stronger, so keep them enabled when possible. If a login form disallows certain characters, turn symbols off and add a few more characters of length to compensate.
- What is a good way to remember these passwords?
- Don't try to memorize random passwords - use a password manager (such as Bitwarden, 1Password, or your browser's built-in one). Generate a unique password for every account, save it in the manager, and you only need to remember one strong master password plus two-factor authentication.
