When you're using Safari, the AutoFill feature will detect when you're typing contact information (such as your name, street address, and so on) or when you're typing a username and password.

When you're typing contact information into a form, AutoFill will automatically type any information into the form automatically, such as your email address or phone number.

But when you're typing a username and password, AutoFill displays a dialog, asking if you want it to remember the username and password for this particular website, as shown in Figure 15-2.

Figure 15-2. The AutoFill feature asks if you want it to memorize your username and password for a particular website.

If you tap Yes, AutoFill will save your username and password for the currently displayed website. If you tap Never for this Website, you'll always have to manually type your username and password. If you're not sure what to do, just procrastinate by tapping Not Now instead.
