Password Security Best Practices
Generating a strong password is step one. Here are 6 more tips to keep your accounts safe.
Use 16+ Characters
Length is the single most important factor in password strength. A 16-character password is exponentially harder to crack than an 8-character one.
Mix Character Types
Combine uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and symbols (!@#$%) for maximum entropy.
Avoid Personal Info
Never use your name, birthday, pet names, or dictionary words. Attackers use these in targeted attacks and dictionary attacks.
Use a Password Manager
Since strong passwords are hard to remember, store them in a trusted password manager like Bitwarden (free & open-source) or 1Password.
Unique Password Per Site
Never reuse passwords. If one site is breached, all your other accounts become vulnerable. Use a unique password for every account.
Enable 2FA Everywhere
Even the strongest password is not enough alone. Enable two-factor authentication on every account that supports it.
Frequently Asked Questions
How does the password generator work?
The password generator uses cryptographically secure random number generation (window.crypto.getRandomValues) directly in your browser to create unpredictable passwords from your chosen character set and length.
Are the generated passwords stored anywhere?
No. Passwords are generated locally in your browser and are never sent to any server. Nothing is logged or stored. Close the tab and the password is gone.
How long should a secure password be?
Security experts recommend at least 16 characters for important accounts. For maximum security, use 20+ characters with a mix of uppercase, lowercase, numbers, and special symbols.
Can I customize the password character set?
Yes. You can choose to include or exclude uppercase letters, lowercase letters, numbers, and special symbols. You can also set the exact password length from 8 to 128 characters.
Is this password generator truly random?
Yes. The tool uses the Web Crypto API (window.crypto.getRandomValues) which is a cryptographically secure pseudorandom number generator (CSPRNG), the same standard used by password managers.
