Smartphones, such as Apple's iPhone, have become everyday tools of modern life, used to pay bills, conduct business, purchase items, and much more. To do all this, we have to repeatedly type in personal information, such as names, email addresses, credit card information, phone numbers, usernames, and passwords.

Luckily, the iPhone's convenient AutoFill feature, which works hand in hand with Safari, prepopulates much of this commonly used data, saving us time and hassle. It's easy to enable AutoFill and add, change, or update the information it pulls.

The instructions here apply to iPhones using iOS 12 and above.
