This tool uses crypto.getRandomValues() — the same random number generator used by security professionals.

Frequently Asked Questions
How long should my password be?
At least 12 characters for general accounts, 16+ for sensitive accounts (banking, email). Longer passwords are exponentially harder to crack. A 16-character password with mixed character types has over 10^30 possible combinations.
Are these passwords truly random?
Yes. This tool uses crypto.getRandomValues(), which provides cryptographically secure random numbers from your operating system. The passwords are generated entirely in your browser and never sent to any server.
Should I use a password manager?
Yes. A password manager lets you use unique, strong passwords for every account without memorizing them. Generate a different password for each site and store them in your password manager.
