^(?![A-Z]+$)(?![a-z]+$)(?!\d+$)(?![\W_]+$)\S{6,16}$

说明：检验密码是含有小写字母、大写字母、数字、特殊符号的两种及以上

正则为(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]+$

不同语言有区别吧?你问的哪种编程语言呢

/(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]{7,20}$/

^(?![A-Z]+$)(?![a-z]+$)(?!\d+$)(?![\W_]+$)\S{6,16}$

(?!^(\d+|[a-zA-Z]+|[~!@#$%^&*?]+)$)^[\w~!@#$%^&*?]+$

你是在java里还是js里，这俩个不同的，你是哪个

js的，特殊符号范围不限，

/^(?![A-Z]+$)(?![a-z]+$)(?!\d+$)(?![\W_]+$)\S{6,16}$/

^(?![A-Z]+$)(?![a-z]+$)(?!\d+$)(?![\W_]+$)\S{6,16}$我觉得是这样
