Why Secure Passwords Matter

In 2024, data breaches exposed billions of records worldwide. The most common entry point? Weak and reused passwords. Using a unique, strong password for every account is one of the simplest and most effective security measures you can take.

Length is more important than complexity. A 16-character password using only lowercase letters (4.3 × 10²² combinations) is actually harder to crack than an 8-character password with mixed case, numbers, and symbols (6.6 × 10¹⁵ combinations). Our generator defaults to 16 characters to ensure robust security.

Passphrases offer the best of both worlds — they're memorable enough to type from memory yet long enough to be extremely secure. A 4-word passphrase drawn from a list of 128 words provides roughly 28 bits of entropy per word, totalling over 112 bits — well beyond what even the most powerful computers can brute-force.

We strongly recommend using a password manager such as 1Password, Bitwarden, or KeePass to store your unique passwords securely. This way you only need to remember one master password, and our tool can help you generate that too.

Frequently Asked Questions

Our password generator uses the Web Crypto API (crypto.getRandomValues()) built into your browser to generate cryptographically secure random values. These values are then mapped to your chosen character sets (uppercase, lowercase, numbers, symbols) to create truly random passwords. All generation happens locally in your browser — no passwords are ever sent to or stored on any server.
