There is support for SQLlite and then there is Apples own ORM layer called Core Data. SQLlite is traditional database access using text commands to "select", "create", "insert" etc.

Core Data will let you save and retrieve entire objects, they also handle memory management for you.

If you only need to save a username and a password maybe a plist file would suffice? I use Core Data for larger data sets and data with different relations.

The reason all these technologies are included is probably that the each have their advantages and problems:)
