The PASS_MIN_DAYS parameter in /etc/login.defs allows an administrator to prevent users from changing their password until a minimum number of days have passed since the last time the user changed their password. It is recommended that PASS_MIN_DAYS
parameter be set to 7 or more days.
Rationale:
By restricting the frequency of password changes, an administrator can prevent users from repeatedly changing their password in an attempt to circumvent password reuse controls.
Parameter:
[7 days]
Technical Mechanism:
Set the PASS_MIN_DAYS parameter to 7 in /etc/login.defs:
PASS_MIN_DAYS 7
Modify active user parameters to match:
# chage -mindays 7 <user>
