Acerca de Password Generator
The strongest password is one you never invent yourself — human patterns are the first thing attackers guess. This generator creates passwords using your browser's cryptographically secure random source (Web Crypto), with full control over length and character sets: upper, lower, digits, symbols, and an option to exclude look-alike characters like 0/O and 1/l. Generated passwords never leave your device — they are created locally, shown locally, and forgotten by the page the moment you leave.
