安全提示：本站生成的密码不经过任何服务器，也不会被记录，请生成后立即存入你自己的密码管理器。长度 16 位以上、混合字符类型的密码，在当前算力下基本无法暴力破解。Security note: passwords are generated entirely on your device and are never logged or transmitted — save them in your own password manager right away. A 16+ character mixed-charset password is practically immune to brute force at current computing power.
