Password Generator

How it works

1. Choose a length and which character types to include.
2. Click Generate.
3. Copy the password to your clipboard.

Supported formats & limitations

• Input
  Length and character-type settings only — no file or personal data.
• Output
  A single random password, shown on screen and copyable.

• Longer passwords with more character types are stronger — the entropy estimate shown is a rough guide, not a guarantee.
• The password is never stored or transmitted; closing or reloading the page discards it.

Frequently asked questions

Is the password sent anywhere? ›

No, it’s generated and displayed entirely in your browser using a cryptographically secure random number generator.

How random is it really? ›

Characters are chosen using the Web Crypto API’s secure random number generator with rejection sampling to avoid bias, not Math.random().

Should I reuse this password across accounts? ›

No — use a unique password for every account, ideally saved in a password manager.

Troubleshooting

Why does clicking Generate show an error? ›

At least one character type (uppercase, lowercase, numbers, or symbols) must stay checked so there’s a character set to generate from.

Why did my copy button say "Copy failed"? ›

Clipboard access can be blocked by browser permissions or an insecure (non-HTTPS) context — select and copy the password manually as a fallback.
