Where to find autofill on Mac and what you can change
Autofill on Mac lives in System Settings under the Safari browser and in iCloud settings. You can turn autofill on or off entirely, choose which types of information autofill remembers (passwords, credit cards, contact details), and delete saved autofill data. The steps differ slightly depending on whether you want to change autofill in Safari, in other browsers like Chrome or Firefox, or in system-wide forms.
Most Mac users encounter autofill in Safari, the built-in browser. Safari stores autofill information in iCloud Keychain, which syncs across your Apple devices. If you use a different browser, each one has its own autofill settings buried in its own preferences menu.
Key Takeaways
- Safari autofill settings are in System Settings > Passwords, not in Safari's own menu.
- You can turn autofill on or off for passwords, credit cards, and contact information separately.
- Deleting a single saved autofill entry requires finding it in Passwords and removing it manually.
- Chrome, Firefox, and other browsers store autofill data in their own settings, not in System Settings.
- iCloud Keychain syncs your Safari passwords and payment methods across all your Apple devices.
How to change autofill in Safari
Open System Settings on your Mac. Click Passwords in the sidebar — you may need to scroll down to find it. At the top of the window, you will see tabs for Passwords, Passkeys, and other categories. The Passwords tab shows all saved passwords and login information.
To change what Safari autofills, look for the settings icon (usually a gear or three dots) in the top right of the Passwords window. Click it and you will see toggles for autofill options: "Autofill passwords and passkeys", "Autofill payment methods", and "Autofill contact information". Turn any of these on or off depending on what you want Safari to remember and suggest.
If you want to delete a single saved password or autofill entry, find it in the list, click it, and look for a delete button or option. You can also right-click the entry and select delete from the menu. Deleted entries will no longer autofill.
How to change autofill in Chrome, Firefox, and other browsers
Chrome and Firefox do not use your Mac's system settings for autofill. Each browser keeps its own autofill data. In Chrome, go to Settings > Autofill and passwords > Passwords. You will see a list of saved passwords and a toggle to turn autofill on or off. Click the three dots next to any saved password to delete it.
In Firefox, go to Settings > Privacy & Security and scroll to Logins and Passwords. You can toggle autofill for usernames and passwords, and click "Saved Logins" to see, edit, or delete individual entries. Firefox also has a separate section for autofill addresses and payment methods under the same Privacy & Security page.
Other browsers like Edge, Opera, and Safari alternatives have similar menus, usually under Settings or Preferences. Look for a section labeled Autofill, Passwords, or Privacy. The exact location varies, but the principle is the same: find the browser's settings, locate the autofill section, and toggle or delete as needed.
How to turn off autofill completely
If you do not want your Mac to remember passwords, payment information, or contact details at all, you can disable autofill entirely. In Safari, open System Settings > Passwords and turn off all the autofill toggles. This stops Safari from suggesting saved information when you fill out forms or log into websites.
Turning off autofill does not delete what is already saved — it only stops the suggestions. If you want to erase all saved passwords and payment methods, you will need to delete them one by one from the Passwords list, or use iCloud settings to remove them across all your devices at once.
How to manage autofill across multiple Apple devices
If you use an iPhone, iPad, and Mac together, your Safari passwords and payment methods sync through iCloud Keychain. Changes you make on one device appear on the others within a few minutes. To control this sync, go to System Settings > [Your Name] > iCloud on your Mac and make sure Keychain is toggled on.
If you want to stop syncing autofill data across devices, turn off iCloud Keychain on any device where you do not want the sync to happen. You can also remove a device from your iCloud account entirely, which will stop it from receiving synced autofill data. Be aware that turning off Keychain sync does not delete the data already on that device — it only stops new changes from syncing.
How to delete all autofill data at once
Safari does not have a single button to clear all autofill data. You must delete passwords and payment methods individually through System Settings > Passwords. However, you can clear your browsing history and website data, which removes some cached information. Go to Safari > Settings > Privacy and click "Manage Website Data" to see what Safari has stored.
If you want a faster way to wipe autofill data, you can reset Safari entirely. Go to Safari > Settings > Advanced and click "Show Develop menu". Then go to Develop > Empty Caches. This clears cached data but does not remove saved passwords — those stay in Keychain unless you delete them manually.
Common autofill problems and how to fix them
If autofill is not working, first check that it is turned on in System Settings > Passwords. Make sure the toggles for the type of information you want to autofill are switched on. If autofill is on but still not appearing, try restarting Safari or your Mac.
If autofill is suggesting the wrong information, you may have duplicate or outdated entries in your Passwords list. Open System Settings > Passwords, search for the website, and delete any old or incorrect entries. Safari will then suggest only the remaining saved password.
If you are using a website that does not work with autofill, it may be because the site uses non-standard form fields that Safari does not recognize. In this case, you will need to type your information manually. Some websites also block autofill for security reasons.
Frequently Asked Questions
Can I autofill different passwords for the same website?
Safari stores only one password per website by default. If you have multiple accounts on the same site, you can save both passwords, but Safari will suggest only the most recently used one. To use a different password, click the password field and Safari will show a dropdown menu with all saved passwords for that site.
Does turning off autofill delete my saved passwords?
No. Turning off autofill toggles only stop Safari from suggesting saved information. Your passwords remain stored in iCloud Keychain. To actually delete them, you must remove them individually from System Settings > Passwords or turn off iCloud Keychain entirely.
Will my autofill data sync if I turn off iCloud Keychain?
No. Turning off iCloud Keychain stops syncing between devices. Your passwords and payment methods will stay on the device where they were saved, but new changes will not sync to your other Apple devices. You can turn Keychain back on at any time to resume syncing.
Can I use autofill in apps other than Safari?
Yes. Many Mac apps can use iCloud Keychain for passwords and payment information if they are built to support it. However, not all apps integrate with Keychain. Apps like Chrome and Firefox use their own autofill systems instead. Check the app's settings to see if it supports iCloud Keychain or has its own autofill feature.
What is the difference between autofill and iCloud Keychain?
Autofill is the feature that suggests saved information when you fill out forms. iCloud Keychain is the find storage system that holds your passwords, payment methods, and contact details. Keychain syncs this information across your Apple devices. You can use autofill without Keychain, but Keychain is what makes autofill work across multiple devices.
