Password Generator

Encode / Decode

Generate secure passwords with custom length, charset, and strength check

Set a length and toggle character sets (uppercase, lowercase, numbers, symbols) to generate passwords matching a specific site's requirements, with a strength meter to sanity-check the result before using it on a real account, and batch generation for setting up several accounts or rotating credentials at once. Generation goes through the browser's `crypto.getRandomValues`, the cryptographically secure API, not `Math.random()`, and nothing is ever transmitted since it all happens client-side. The strength meter estimates entropy from length and character-set diversity; it isn't checking against real-world breach databases, so treat it as a guideline rather than a guarantee. The output is meant to be used once per site and stored in a password manager, not reused or memorized across accounts.

How to use Password Generator

  • 1.Set a length and toggle character sets (uppercase, lowercase, numbers, symbols) to generate a password matching a specific site's requirements.
  • 2.Check the strength meter after generating to confirm the password resists common cracking approaches before using it on a real account.
  • 3.Generate several passwords at once when setting up multiple new accounts or rotating credentials across services.

Frequently asked questions

Are these passwords generated securely?
Yes, generation uses the browser's Web Crypto API (`crypto.getRandomValues`), which is cryptographically secure — not `Math.random()`.
Is my generated password sent to a server?
No, passwords are generated and displayed entirely client-side and never transmitted anywhere.
How is "strength" calculated?
Strength is estimated from length and character set diversity (entropy), not from checking against real-world breach databases — it's a good guideline, not a guarantee.
Should I reuse a generated password across sites?
No — generate a unique password per site and store them in a password manager rather than reusing or memorizing them.
