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
- Drag the slider to set length (16–32 is recommended)
- Check which character types to include
- Click "Generate"; the result auto-copies to your clipboard
Use Cases
- Creating a strong password for a new account
- Bulk-generating temporary passwords for team members
- Initial setup of DB / SSH / root credentials
- Generating API keys or shared secrets (pair with UUID generator)
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).

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