To change how long a user's account can be inactive before it is locked, use the usermod command. For example, to set the inactivity period to 30 days:
# usermod -f 30 username
To change the default inactivity period for new user accounts, use the useradd command:
# useradd -D -f 30
A value of -1 specifies that user accounts are not locked due to inactivity.
For more information, see the useradd(8)
and
usermod(8)
manual pages.
