Change AutoFill settings in Safari on Mac
In the Safari app on your Mac, use AutoFill settings to fill in contact information, user names and passwords, credit card information, and other forms on webpages.
To change these settings, choose Safari > Settings, then click AutoFill.
Using information from my contacts
Complete forms with information from any contact card in Contacts. To view or edit information, click Edit.
User names and passwords
Save user names and passwords you enter on websites, then easily fill in the saved information when you revisit the same websites.
Click Edit to view or edit your saved information.
Save your name as it appears on the card, the card number, expiration date, and security code, then easily fill in the saved information when you use the card again.
When you add a credit card in AutoFill settings, the security code is optional. When you add a previously unsaved credit card while making a purchase, the security code is required.
Important: Saving the security code with your card makes purchases convenient, but anyone with access to your Mac can make purchases with the card.
Click Edit to add or remove saved credit cards, or to change the information for a saved credit card.
If you have cards in Wallet, they also appear in the list. See Use Wallet & Apple Pay.
Note: If you set up iCloud Keychain to autofill information on your Mac and other Apple devices, you can use AutoFill to enter previously saved credit card info on all those devices.
Save information you enter on webpage forms, then easily fill in the saved information when you revisit the same webpages.
Click Edit to see or remove websites for which Safari has saved AutoFill information.
