How the Password Generator Works
Passwords are generated entirely in your browser using crypto.getRandomValues() — the same cryptographic engine used for HTTPS. No data is sent to any server. Adjust length and character types with the options below; the strength bar rates the result based on entropy (length × character diversity).
Password Security Best Practices
- Use at least 16 characters. Length is the single most important factor. A 16-character password takes orders of magnitude longer to brute-force than a 10-character one. Aim for 20+ on high-value accounts.
- Never reuse passwords across accounts. If one service is breached, attackers try the same credentials everywhere else. Unique passwords contain the damage.
- Use a password manager. You cannot memorize 50 unique 20-character passwords. Tools like Bitwarden (free, open-source), 1Password, and KeePass store and autofill securely.
- Enable two-factor authentication (2FA) wherever possible. Even if someone obtains your password, a second factor blocks access. Prioritize email, banking, and social accounts.
Frequently Asked Questions
Are the generated passwords truly random?
Yes. The generator uses
crypto.getRandomValues() — the same cryptographic random number generator your browser uses for HTTPS. This is fundamentally different from Math.random(), which is not cryptographically secure. The output is indistinguishable from true randomness for practical purposes.Is it safe to generate passwords in a browser?
Yes — everything runs locally on your device. No password is ever sent to a server, logged, or stored anywhere outside your clipboard. You can even load this page, disconnect from the internet, and the generator will continue to work. The only risk would be malware running on your own machine.
How long should my password be?
16 characters is the recommended minimum for most accounts. 12 characters is the absolute floor for anything important. For critical accounts — email, banking, primary password manager — aim for 20 or more characters. The extra length costs you nothing (your password manager remembers it) and makes brute-force attacks computationally infeasible.
