Password Generator — Strong Random Passwords Online

About this tool

Weak passwords are the #1 cause of data breaches. This tool generates cryptographically strong passwords using the browser's crypto.getRandomValues() — not Math.random(). Customize length (4–128) and character sets (uppercase, lowercase, digits, symbols). 100% local; nothing is uploaded.

How to use

  1. Drag the slider to set length (16–32 is recommended)
  2. Check which character types to include
  3. Click "Generate"; the result auto-copies to your clipboard

Use Cases

FAQ

Q: Truly random?
A: Yes — uses crypto.getRandomValues() (CSPRNG), not Math.random().

Q: How is strength measured?
A: Length × charset entropy. 16 chars from all 95 printable = ~95 bits = 10²⁰ years to brute-force.

Q: Can passwords repeat?
A: Statistically impossible. 32 chars from full charset = 2²⁰⁰+ possibilities.

Tips & Related Tools

Best practice: unique password per account, stored in a manager (Bitwarden, 1Password).

Never email, chat, or write passwords on sticky notes.

Enable 2FA — defense in depth even if a password leaks.
