How to Enable or Change AutoFill Information on an iPhone

Update AutoFill for personal info, credit cards, passwords, and more

Smartphones, such as the Apple iPhone, are used every day to pay bills, conduct business, purchase items, and more. To do all this, you repeatedly type personal information, such as names, email addresses, credit card information, phone numbers, usernames, and passwords. The iPhone AutoFill feature, which works with Safari, prepopulates much of this commonly used data. It's easy to enable AutoFill and add, change, or update the information it pulls.

The instructions in this article apply to iPhones with iOS 12 and above.

  4. Turn on the Use Contact Info toggle switch.
