PASSWD(1)		  BSD General Commands Manual		     PASSWD(1)

NAME
     passwd — modify a user's password

SYNOPSIS
     passwd [-l] [user]

DESCRIPTION
     Passwd changes the user's Kerberos password.  First, the user is prompted
     for their current password.  If the current password is correctly typed,
     a new password is requested.  The new password must be entered twice to
     avoid typing errors.

     The new password should be at least six characters long and not purely
     alphabetic.  Its total length must be less than _PASSWORD_LEN (currently
     128 characters).  Numbers, upper case letters and meta characters are
     encouraged.

     Once the password has been verified, passwd communicates the new password
     information to the Kerberos authenticating host.

     -l	   This option causes the password to be updated only in the local
	   password file, and not with the Kerberos database.  When changing
	   only the local password, pwd_mkdb(8) is used to update the password
	   databases.

     To change another user's Kerberos password, one must first run kinit(1)
     followed by passwd(1).  The super-user is not required to provide a
     user's current password if only the local password is modified.

FILES
     /etc/master.passwd	 The user database
     /etc/passwd	 A Version 7 format password file
     /etc/passwd.XXXXXX	 Temporary copy of the password file
