When altering a password, the program prompts for the current password and then for the new one. The caller must supply both. The new password must be typed twice to forestall mistakes.
New passwords must be at least four characters long if they use a sufficiently rich alphabet and at least six characters long if monocase. These rules are relaxed if you are insistent enough.
Only the owner of the name or the super-user may change a password; the owner must prove he knows the old password.
Use yppasswd to change your password in the network yellow pages. This will not affect your local password, or your password on any remote machines on which you have accounts.
