    The primary or the secondary key.  If you want to change the key(which is probably a good idea to
    do every once in a while in case it gets leaked somehow), you would have some downtime if there 
    was only one key available.  So you get two, the primary and the secondary.If you disable one 
    key the other key will still work giving you time to replace the disabled one.
