About this secure password generator

Strong passwords have three properties: they are long, they avoid dictionary words, and they are unique to each account. Length is the most important — a 20-character random password is dramatically harder to crack than a 10-character one, even if both look complex.

The generator uses the browser built-in cryptographic random number generator (`crypto.getRandomValues`). This is the same source of randomness used for HTTPS keys — orders of magnitude better than Math.random() and acceptable for any non-classified use.

A password manager is the best place to store generated passwords. Reusing a single complex password across multiple sites defeats the purpose of complexity — if any one of those sites is breached, every account using the same password is compromised. Generate a unique password per account and let the manager remember them.

How to use it

  1. Choose a length — 14+ characters is a reasonable floor; 20+ is better for important accounts.
  2. Tick which character types to include — leaving symbols off can be useful for sites that reject special characters.
  3. Click Regenerate for a new password.
  4. Copy and paste into your password manager.

Tips & notes

  • Use a password manager (Bitwarden, 1Password, KeePass) to store generated passwords. Memorising them is impractical.
  • For very high-value accounts (banking, email), use 24+ characters and a passphrase backup option.
  • Avoid character types that the target site rejects. Some banks ban specific symbols and you do not want to find out after copying.

Frequently asked questions

Are the generated passwords stored anywhere?

No. They are generated in your browser using the Web Crypto API and are not transmitted, logged or saved.

How long should a password be?

For most accounts, 14+ characters with mixed case, digits and symbols. For critical accounts (email, banking, password manager itself), 20+ characters and a unique passphrase backup.

Why does the strength meter sometimes drop with longer passwords?

The meter checks length and character mix. A 30-character password with only lowercase letters scores lower than a 20-character password with mixed types — because adding character classes increases the entropy faster than length alone.

Should I use the same password across multiple accounts?

No. Password reuse is the single biggest cause of account compromise. Use a password manager and a unique password per account.
