You can't "access" the superuser password. In addition to being stored in a file only readable by the superuser, its also encrypted in a one-way hash. This means that it is not stored in plaintext, and the computer checks to see if the password is correct by encrypting the supplied password and seeing if the hash matches, not just comparing the passwords sirectly.

Superuser can override file security and do almost anything he/she wants on the system (he/she cannot see your password, since it is encrypted, but he/she can change it). In fact, any user with a useridof 0 is a superuser. Naturally, such users should always have a password.It is not good practice for the system administrator to always logon as superuser. It is too easy to make a trivial mistake and damage the system, perhaps by rm * in an important directory.
