Password Generator

How to create a strong password

1. Use at least 16 characters
2. Mix uppercase, lowercase, numbers, and symbols
3. Avoid dictionary words or personal information
4. Use a unique password for every account
5. Use a password generator instead of creating one manually

Why use a password generator?

Humans are bad at creating random passwords. We tend to use predictable patterns, dictionary words, and personal details that attackers can guess. A password generator uses cryptographic randomness to create truly unpredictable passwords that are virtually impossible to crack by brute force.

This tool uses your browser's built-in crypto.getRandomValues() API for cryptographically secure random number generation. Your password is generated entirely on your device — it is never sent to any server.

Frequently Asked Questions

Is this password generator safe?

Yes. This tool runs entirely in your browser. Your generated password never leaves your device — no network requests are made. It uses crypto.getRandomValues(), the same cryptographic API used by password managers.

How long would it take to crack a 16-character password?

A 16-character password using uppercase, lowercase, numbers, and symbols has about 95^16 possible combinations. At 100 billion guesses per second, it would take over 3 billion years to brute-force — making it effectively uncrackable.

Should I use a different password for every account?

Absolutely. If you reuse passwords and one service is breached, attackers will try that password on your other accounts (credential stuffing). Use a unique password for each account and store them in a password manager.
