Hello, bro,
wish you can consider my solution.
V100R003 version can support to configure the Password Validity Period of the admin User
you can do it as following steps:

1.Click the admin user
2.Set Password validity (days) and Password expiration notification interval (days)
When Password validity (days) is set to 0, the password is valid permanently. The Password expiration notification interval (days) parameter indicates the number of days before password expiration to instruct the user to change the password. For example, if Password expiration notification interval (days) is set to 7, the system instructs the user to change the password when the password is about to expire in seven days.
3.Click OK.
