Colon-delimited file containing password hashes for every user listed in /etc/passwd

$USERNAME:$PASSWORD:$LASTCHANGED:$MIN:$MAX:$WARN:$INACTIVE:$EXPIRE

• $USERNAME Login name
• $PASSWORD Encrypted password; dollar signs delimit encryption hash function ($1, $2a, $2y, $5, or $6), then salt, then hash value. After locking the account with usermod -L, an exclamation point ! is placed in front of this field, making the password inoperable and locking the account. When an account has not yet had a password set, this value is !!
• $LASTCHANGED Days since 01/01/1970 that password was last changed
• $MIN minimum number of days required between password changes
• $MAX maximum number of days the password is valid before user is forced to change password
• $WARN number of days the password is to expire that user is warned that password must be changed
• $INACTIVE number of days after password expires that account is disabled
• $EXPIRE days since 01/01/1970 that account is disabled
