推荐答案

您的问题不明确，您希望在 6天或60天后 ????



您必须设置一个名称为 UpdatedAt（DateTime）在您的数据库表中更新密码。

登录时您必须检查更新日期和当前日期之间的差异是否大于6或60，而不是必须显示消息，您必须更改密码



您可以通过此查询获得差异





Your question is not clear ,you want it after 6 days or 60 days????

You have to set one field having name UpdatedAt(DateTime) in your database table in which password is updated.
at a time of login you have to check if the difference between updated date and current date is greater than 6 or 60 as you want than you have to show message that you have to change password

you can get difference by this query

select datediff(day,updateAt,GETDATE()) AS TimeDiff

继续What What rav建议，我建议在用户表中添加像[PasswordChangeDate]这样的显式字段，因为在标准设计中，表通常有UpdatedAt字段，如果User表中有更改，则必须更新。 PasswordChangeField只会在用户更改密码时更新。

In continuation of What Nirav has suggested, i would suggest to add an explicit field like [PasswordChangeDate] in the User Table as in standard design a table usually have UpdatedAt field which necessarily gets updated if there is a change in the User table. PasswordChangeField will only get updated when a user change password.

您只需要在存储密码更改的最后日期的表中使用日期字段说lastUpdate。每次用户登录时，检查当前日期与他的lastUpdate，

1.如果差异是< 60天，让他通过。

2.如果差异是> = 60天但是<= 66天，提示他更改密码但继续允许他登录，

3.否则，如果是> 66天，拒绝任何登录，直到他更改密码。

You just need a date field say lastUpdate in a table that stored the last date of password change. Every time a user logs in, check the current date against his lastUpdate,
1. if the difference is < 60 days, let him through.
2. if the difference is >= 60 days but <= 66 days, prompt him to change password but continue to allow him to log in,
3. else if it is > 66 days, reject any log in until he changes his password.
