+config FEATURE_SHADOWPASSWDS
+ bool "Support for shadow passwords"
+ default n
+ help
+ Build support for shadow password in /etc/shadow. This file is only
+ readable by root and thus the encrypted passwords are no longer
+ publicly readable.
+
+config USE_BB_SHADOW
+ bool " Use busybox shadow password functions"
+ default y
+ depends on USE_BB_PWD_GRP && FEATURE_SHADOWPASSWDS
+ help
+ If you leave this disabled, busybox will use the system's shadow
+ password handling functions. And if you are using the GNU C library
+ (glibc), you will then need to install the /etc/nsswitch.conf
+ configuration file and the required /lib/libnss_* libraries in
+ order for the shadow password functions to work. This generally
+ makes your embedded system quite a bit larger.
+
+ Enabling this option will cause busybox to directly access the
+ system's /etc/shadow file when handling shadow passwords. This
+ makes your system smaller and I will get fewer emails asking about
+ how glibc NSS works). When this option is enabled, you will not be
+ able to use PAM to access shadow passwords from remote LDAP
+ password servers and whatnot.
+
+config USE_BB_PWD_GRP
+ bool "Use internal password and group functions rather than system functions"
+ default n
+ help
+ If you leave this disabled, busybox will use the system's password
+ and group functions. And if you are using the GNU C library
+ (glibc), you will then need to install the /etc/nsswitch.conf
+ configuration file and the required /lib/libnss_* libraries in
+ order for the password and group functions to work. This generally
+ makes your embedded system quite a bit larger.
+
+ Enabling this option will cause busybox to directly access the
+ system's /etc/password, /etc/group files (and your system will be
+ smaller, and I will get fewer emails asking about how glibc NSS
+ works). When this option is enabled, you will not be able to use
+ PAM to access remote LDAP password servers and whatnot. And if you
+ want hostname resolution to work with glibc, you still need the
+ /lib/libnss_* libraries.
+
+ If you enable this option, it will add about 1.5k to busybox.

+ Note that Busybox binary must be setuid root for this applet to
+ work properly.

+config LOGIN_SCRIPTS
+ bool "Support for login scripts"
+ depends on LOGIN
+ default n
+ help
+ Enable this if you want login to execute $LOGIN_PRE_SUID_SCRIPT
+ just prior to switching from root to logged-in user.
+
+config FEATURE_SECURETTY
+ bool "Support for /etc/securetty"
+ default y
+ depends on LOGIN
+ help
+ The file /etc/securetty is used by (some versions of) login(1).
+ The file contains the device names of tty lines (one per line,
+ without leading /dev/) on which root is allowed to login.
+
+config PASSWD
+ bool "passwd"
+ default n
+ select FEATURE_SUID
+ select FEATURE_SYSLOG

+ passwd changes passwords for user and group accounts. A normal user
+ may only change the password for his/her own account, the super user
