What is Password Generator?

Generate cryptographically strong passwords that respect your specific requirements: length, character classes (lowercase, uppercase, digits, symbols), and whether to exclude ambiguous characters (like O and 0). Uses the browser's Web Crypto API (crypto.getRandomValues), not Math.random; so the output is genuinely unpredictable, not just pseudo-random. Generate multiple at once for a whole rotation.

How do I use Password Generator?

1. Set the length (12-64 recommended).
2. Toggle character classes: lowercase, uppercase, digits, symbols.
3. Click Generate for a fresh password.
4. Copy or download the output.

Common use cases for Password Generator

• Generating a 20-character Wi-Fi password for a small-office router.
• Creating a unique password per site for use in a password manager.
• Producing a memorable 5-word diceware passphrase for a master password.
• Spinning up 50 user seeds for a staging database.
• Getting a numeric PIN of exact length for a device lock.

Common pitfalls and how to avoid them

• Same password appears twice — Each click produces a fresh generation. If you see duplicates, you copied the old buffer; click Regenerate and copy again.
• Site rejects the password — Check the site's allowed characters. Toggle off symbols (or specific ones) to match their policy.
• Forgot the password after closing — We never store passwords. Paste into a password manager (1Password, Bitwarden, KeePass) before leaving the page.

When should I use Password Generator?

Password Generator is for creating new passwords. To check the strength of an existing password, use Password Strength. For hashing rather than generating, use Hash Generator.
