How long should a password be?

Security experts recommend at least 12 characters for general accounts and 16+ for sensitive accounts like banking or email. Longer passwords are exponentially harder to crack.

Is this password generator secure?

Yes. CalcBright uses the Web Cryptography API (crypto.getRandomValues) which is cryptographically secure — unlike many tools that use Math.random(). Passwords are never sent to a server.

Password Generator FAQ

Common questions about password security.

Is this password generator truly secure?

Yes. We use the browser's Web Cryptography API (crypto.getRandomValues), which is cryptographically secure and approved for security-sensitive applications. Passwords are generated entirely in your browser — we never see or store them.

How long should my password be?

At least 12 characters for most accounts, and 16+ for banking, email, and other sensitive accounts. A 16-character password using all character types would take centuries to brute-force crack.

Should I use a password manager?

Absolutely. A password manager (like Bitwarden, 1Password, or Dashlane) stores all your unique passwords securely and autofills them. This means you only need to remember one strong master password.

What makes a password strong?

A strong password is long (16+ characters), random, and uses a mix of uppercase letters, lowercase letters, numbers, and symbols. It should not contain dictionary words, personal information, or repeat patterns.
