Revealed: How Apple creates your passwords

The automatically suggested passwords on iPhone and Mac look like random characters, but there's a sophisticated system at work.

When you log into a new service or website on an iPhone, iPad, or Mac, the operating system will promptly suggest a ready-made password that you can accept or reject. This password will be quite long; it will not contain any recognizable words; and it will contain special characters such as hyphens and numbers. All of this fulfills the requirements for passwords so that attackers cannot crack them easily by brute force, simply guessing common combinations of characters.
