Strong Password Generator — Uncrackable Passwords
Generate strong, uncrackable passwords with uppercase, lowercase, numbers, and symbols. Cryptographically secure — runs locally in your browser.
Create passwords that would take billions of years to crack. This generator uses your browser's crypto API to produce truly random, high-entropy passwords. Customize length (8-128 characters), include symbols, numbers, and mixed case for maximum security.

Click Generate to create a random password. Adjust length using the slider (6–64 characters) and toggle character types: uppercase, lowercase, numbers, and symbols. A strength meter shows password security.
The generator uses the Web Crypto API — the same cryptographically secure random number generator used by banks and security software. Your password is created entirely in your browser and is never transmitted anywhere.
