Generate cryptographically secure passwords — customizable length and character sets. Never stored or transmitted.
Password strength is measured by entropy — the number of possible combinations an attacker must try. Each additional character and character type exponentially increases the attack space.
A 12-character password using all character types has ~72 bits of entropy — taking decades to crack by brute force. A 20-character password has ~123 bits — effectively uncrackable with current hardware.
Yes. This tool uses the browser's crypto.getRandomValues() API, which provides cryptographically secure random numbers — the same source used by security-focused applications. It is significantly more secure than Math.random().
All password generation happens entirely in your browser. No generated password is ever sent to a server, logged, or stored anywhere. Close the tab and the password is gone.
