Strong Password Generator
What is Strong Password Generator
A strong password generator creates cryptographically random passwords that are resistant to brute-force and dictionary attacks. This tool lets you choose length and character sets to create passwords that meet any security requirement.
How to use
- Adjust the password length using the slider (8–64 characters).
- Check or uncheck character types: uppercase, lowercase, numbers, symbols.
- The password is generated instantly. Click Regenerate for a new one.
- Click Copy to copy the password to your clipboard.
When to use it
Signing up for a bank or online store? Generate a 20-character password with every character type turned on, then save it in your password manager so you never have to memorize it. Each account gets its own unique password, which is what keeps one leak from unlocking the rest.
Frequently asked questions
Is this password generator truly random?
Yes. It uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers in the browser.
Is my password stored anywhere?
No. All generation happens locally in your browser. No password is ever sent to a server.
How long should my password be?
For most accounts, 16–20 characters is excellent. For high-value accounts, use 24+ characters with all character types.
