### Accounts and Passwords ### Accounts and Passwords
Within the xspasswd/ directory is a password-setting utility. XS uses its own password file distinct from the system /etc/passwd to authenticate clients, using standard bcrypt+salt storage. This is currently done to allow alternate login credentials via xs vs. console/ssh login, due to the experimental nature of the program. At some point in the future an option to use the system's /etc/passwd and /etc/shadow may be implemented, making the use of the auxilliary xspasswd utility optional or obsolete. Within the ```xspasswd/``` directory is a password-setting utility, ```xspasswd```, used if one wishes ```xs``` access to use separate credentials from those of the default (likely ssh) login method. In this mode, ```xsd``` uses its own password file distinct from the system /etc/passwd to authenticate clients, using standard bcrypt+salt storage. Activate this mode by invoking ```xsd``` with ```-s false```.
