How to Use Enhanced AutoFill on an iPhone, iPad

In the Safari app on the iPhone and iPad, you can use AutoFill to automatically fill in credit card information, contact information, and user names and passwords. Let’s look how to do it in iOS 17 and iPadOS 17.

Set up AutoFill

You can save your personal information or credit card number on your iPhone or iPad to speed up filling in online forms and making purchases.

1. Go to Settings  > Safari > AutoFill.
2. Do any of the following:
   • Set up contact info: Turn on Use Contact Info, tap My Info, then choose your contact card. The contact information from that card is entered when you tap AutoFill on webpages in Safari.
   • Set up credit card info: Turn on Credit Cards, tap Saved Credit Cards, then tap Add Credit Card. Enter your credit card information into the fields provided or tap Use Camera to enter the information without typing.

Fill in your contact information automatically

You can quickly add your personal information to online forms using AutoFill.

1. In a form on a website that supports AutoFill, tap a blank field.
2. Tap AutoFill Contact above the keyboard, then select a contact.
3. Tap any field to make changes.
4. When all the information is correct, tap Done.
5. Follow the onscreen instructions to submit the form.

Note: You can AutoFill another person’s information from your contact list. For example, if you’re purchasing a gift and shipping it to a friend, you can use AutoFill to enter their address. Tap AutoFill Contact, tap Other Contact, then choose their contact card.

Fill in your credit card information automatically

After you add a credit card, you can use AutoFill to make online purchases without having to enter your full credit card number.

1. Tap the credit card information field.
2. Tap the saved credit card you want to use, or tap Scan Card to take a picture of the front of the card.
   Tip: After you enter a new card, you can save it in Safari Autofill, then add it to Wallet.

You can use virtual card numbers at checkout and keep your real credit card number private. After you’ve set up a virtual card number, tap a card with the Wallet app above the keyboard to use it at checkout.

Automatically fill in strong passwords

When you sign up for services on websites and in apps, you can let iPhone create and save strong passwords for many of your accounts. 

Turn off AutoFill

You can turn off AutoFill for your contact or credit card information, and for passwords. This is helpful in situations where you don’t want your contact or credit card information to be readily available—for example if you share a device with others.

• Turn off AutoFill for your contact or credit card information: Go to Settings  > Safari > AutoFill, then turn off either option.
• Turn off AutoFill for passwords: Go to Settings > Passwords, unlock the screen, tap Password Options, then turn off AutoFill Passwords and Passkeys.

Also, pay attention to Apple’s warning to never enter your password or credit card number on sites with a “Not Secure” warning.
