Did you try looking at the Javadoc for ArrayList for a method that might give you the index Of an object ?
Of course, a better solution would be to create a class to hold your username and password and just add instances of this class to the ArrayList. You will need to override the equals() and hashCode() methods in your class in order to retrive the instances from the ArrayList. A bit more work, but when you come to add more attributes to your user it will make life a lot easier,
