What Makes This Generator Secure
The password generator uses window.crypto.getRandomValues() — the browser's cryptographically secure pseudo-random number generator (CSPRNG). This is the same entropy source used by cryptographic software and is far more unpredictable than standard Math.random().
Password Strength Guide
Weak (under 10 chars, one type): vulnerable to brute force
Fair (10–12 chars, 2 types): adequate for low-risk accounts
Strong (14–16 chars, 3+ types): recommended minimum
Very Strong (20+ chars, all types): use for critical accounts
Best Practices
- Use a unique password for every account — never reuse passwords.
- Store passwords in a reputable password manager (Bitwarden, 1Password, etc.).
- Enable two-factor authentication wherever available.
- Use 16+ character passwords for email, banking, and cloud storage accounts.
Questions fréquentes
Are passwords generated by this tool stored anywhere?
No. The password generator runs entirely within your browser using JavaScript. Generated passwords never leave your device, are never sent to any server, and are never logged or stored. The moment you close the tab, they are gone.
What makes a password strong?
A strong password is long (16+ characters), uses a mix of uppercase letters, lowercase letters, numbers, and symbols, avoids common dictionary words, and is unique (not reused across accounts). This tool gives you all of these by default.
How often should I change my passwords?
Security guidance has evolved. Current best practice (NIST guidelines) recommends changing passwords only when there is reason to believe they may have been compromised, rather than on a fixed schedule. The most important thing is to use unique, strong passwords and a password manager.
Should I use a password manager?
Yes. A password manager allows you to use a unique, complex password for every account without needing to remember them all. You only need to remember one strong master password. This is the single most impactful step you can take to improve your online security.
