生成安全的随机密码，支持自定义长度和字符类型
Strong passwords are your first line of defense against unauthorized access. This free online password generator creates cryptographically secure random passwords using the Web Crypto API. Customize password length, character types (uppercase, lowercase, numbers, symbols), and generate multiple passwords at once. A visual strength meter shows how secure your generated password is. All generation happens locally in your browser — no passwords are ever transmitted or stored.
Set your desired password length and select which character types to include, then click "Generate". Adjust settings until the strength meter shows your desired security level, then copy the password with one click.
