How to Create a Strong Password

A strong password is your first line of defense against unauthorized access to your accounts. With data breaches becoming increasingly common, using a unique, complex password for every account is more important than ever.

Tips for Strong Passwords

  • Use at least 16 characters. Longer passwords are exponentially harder to crack. Every additional character multiplies the number of possible combinations.
  • Mix character types. Combine uppercase letters, lowercase letters, numbers, and symbols for maximum entropy.
  • Avoid personal information. Never use names, birthdays, pet names, or common words. Attackers use dictionaries and social engineering to guess these.
  • Use a unique password for every account. If one password is compromised, all your other accounts remain safe.
  • Use a password manager. A password manager generates and stores complex passwords so you only need to remember one master password.

What Makes a Password Weak?

  • Short passwords (fewer than 12 characters)
  • Common words or phrases ("password123", "qwerty")
  • Sequential numbers or letters ("abc123", "111111")
  • Personal information (names, dates, addresses)
  • Reusing the same password across multiple sites

How PassGenPro Keeps You Secure

PassGenPro generates cryptographically secure random passwords using your browser's built-in crypto.getRandomValues() API. This means:

  • No data leaves your browser. Passwords are generated entirely on your device. Nothing is sent to any server.
  • Cryptographically secure randomness. We use the Web Crypto API, the same standard used by banks and security applications.
  • No tracking or storage. PassGenPro does not store, log, or track any generated passwords.

Frequently Asked Questions

Is this password generator safe to use?

Yes. All passwords are generated locally in your browser using cryptographically secure random number generation. No passwords are transmitted or stored anywhere.

How long should my password be?

We recommend at least 16 characters for most accounts. For high-security accounts (banking, email), consider 20 or more characters.

What are ambiguous characters?

Ambiguous characters like 0 (zero) and O (letter), or l (lowercase L) and 1 (one) can be confused when reading a password. Excluding them makes passwords easier to type manually.

Should I use a password manager?

Absolutely. A password manager lets you use a unique, strong password for every account without memorizing them. Popular options include Bitwarden, 1Password, and KeePass.
