M2 禁用修改管理员密码(It’s time to change your password)

每隔一段时间，后台登录后，总是提示:

It’s time to change your password

并且必须得修改，密码还不能用之前设置过的。不然去不了其他页面。

修改如下:

1. Change expires value in PhpMyAdmin

run this sql query:

1	1 UPDATE admin_passwords SET expires = 1999999998 WHERE user_id = <<admin_user_id>>;

Or you can change expires value direct in table admin_passwords as my screen bellow

2.Change settings in backend to this issue does not appear again.

First, You need login in backend with your admin account. then go to Stores > Configuration, Click ADVANCED > Admin > Security on left section.

On the next step, You need set Password Change to Recommended
