手机密码能设置为汉字吗？
日常生活中，密码使用很常见了。基本上，登录APP、手机支付、开机解锁，都需要使用密码，数字密码，指纹密码，字母密码，各种的密码唯独没有汉字。
为什么密码不用汉字呈现？是中华文化太博大吗？
“为什么密码不能设置汉字？”
1.实现难度较大。其实密码是可以设置成汉字的，不过密码是加密储存，一般情况下加密算法是针对字节而加密，一个英文、数字和符号只占用一个字符，这样可以较快速地加密，然后将密码提交到数据库当中。

2.人为限制。被人为限制，设置密码时无法选择输入法，从而无法输入汉字。
3.使用习惯。大部分人拥有较强的安全意识，会使用英文字母大小写、数字和符号组合而成的密码，这样设置的密码安全性较高。

4.密码统一。英文和阿拉伯数字是目前世界上较为通用的文字和数字，使用它们设置密码可以更换地统一世界的密码使用标准。
以上，就是为什么密码没有汉字的主要原因。
总结一下，就是——
可以，但没必要
