Generate a strong, random password instantly using your chosen length and character types. Everything happens in your browser using a cryptographically secure random number generator, so your password is never sent anywhere.
How This Password Generator Works
Adjust the length slider and choose which character types to include, then click "Generate New Password" or change any setting to create a new one instantly. The strength meter below the password gives a quick visual read on how strong your chosen combination is. Click "Copy" to copy the password to your clipboard.
What Makes a Password Strong
- Length matters most. A longer password is exponentially harder to crack than a shorter one, even with fewer character types. Aim for at least 12 to 16 characters when the site allows it.
- Mix character types. Combining uppercase letters, lowercase letters, numbers, and symbols increases the number of possible combinations an attacker would need to try.
- Avoid reused passwords. Use a unique password for every account. If one site is breached, a reused password puts every other account at risk too.
- Use a password manager. Since strong random passwords are hard to remember, a password manager lets you generate and store unique passwords for every site without having to memorize them.
Is This Tool Safe to Use?
Yes. This generator runs entirely in your browser using the Web Crypto API, which is the same secure randomness source used by browsers for cryptographic operations. Your generated password is never transmitted, logged, or stored anywhere, including by this website.
Frequently Asked Questions
Is this password generator free to use?
Yes, completely free with no limit on how many passwords you can generate, and no account is required.
Does this tool store or send my generated password anywhere?
No. Everything happens directly in your browser using JavaScript's built-in secure random number generator. Nothing is sent to a server or saved anywhere.
Why should I exclude similar characters?
Characters like lowercase L, uppercase I, and the number 1 can look identical in some fonts. Excluding them helps avoid mistakes when you need to type the password manually instead of pasting it.
How long should my password be?
Most security experts recommend at least 12 to 16 characters with a mix of character types. For highly sensitive accounts, consider going even longer if the platform supports it.
