Where to find and change autofill on iPhone

Autofill on iPhone lives in Settings under Passwords, then Autofill. Open Settings, scroll down to Passwords (or Passwords & Security on newer iOS versions), tap it, then toggle Autofill Passwords on or off. If you want autofill to work for credit cards, usernames, or addresses instead of passwords, those settings are in a different place — they're under Settings > General > Autofill, where you can turn on or off Credit Cards, Contacts, and Usernames & Passwords separately.

The reason Apple split these settings is that password autofill uses iCloud Keychain (Apple's encrypted password vault), while the other autofill types pull from your Contacts app and saved payment methods. Understanding which setting controls what saves you from thinking autofill is broken when it's just turned off in the wrong menu.

Key Takeaways

  • Password autofill is in Settings > Passwords, while credit card and address autofill is in Settings > General > Autofill.
  • You can turn autofill on or off for passwords, credit cards, contacts, and usernames independently — you don't have to use all of them.
  • If autofill isn't appearing when you expect it, check that Face ID or Touch ID is enabled, because iPhone won't autofill without biometric verification.
  • Autofill suggestions come from your iCloud Keychain (passwords), your Contacts app (addresses and names), and your saved payment methods (cards).

Turning password autofill on and off

Open Settings and scroll to Passwords (on iOS 17 and later, it's Passwords & Security). Tap it. At the top, you'll see "Autofill Passwords" with a toggle switch. Flip it on to let Safari and apps autofill your saved passwords; flip it off to disable the feature entirely. When autofill is on, iPhone will ask you to verify with Face ID, Touch ID, or your passcode before filling in a password — that's a security feature, not a bug.

If you want to keep autofill on but prevent it from working in certain apps, you can't do that from Settings. Instead, go into each app's own settings and look for a privacy or autofill option there. Some apps let you disable autofill locally even when it's on system-wide.

Managing credit card and address autofill

Credit card and address autofill is separate from password autofill. Go to Settings > General, scroll down, and tap Autofill. You'll see three toggles: Credit Cards, Contacts, and Usernames & Passwords. Turn any of these on or off depending on what you want autofilled.

For credit cards, iPhone pulls from cards you've saved in Wallet. To add or remove a card from autofill, go to Settings > Wallet & Apple Pay, tap the card, and look for autofill options. For addresses, iPhone uses information from your Contacts app — specifically, your own contact card. Make sure your address is saved there if you want it to autofill.

Why autofill isn't showing up

If you've turned autofill on but it's not appearing when you tap a password or credit card field, the most common reason is that biometric verification isn't set up. iPhone requires Face ID or Touch ID to autofill passwords for security. If you don't have either enabled, go to Settings > Face ID & Passcode (or Touch ID & Passcode) and set one up.

Another reason autofill might not appear is that the website or app doesn't recognize the field as a password or payment field. Some older websites use non-standard code that iPhone can't detect. In that case, you can still copy and paste from your Keychain manually — open Settings > Passwords, find the entry, and copy the password.

If autofill is on but a specific password or card isn't showing up, it may not be saved in your Keychain or Wallet. Check Settings > Passwords to see what's actually stored, and add any missing passwords or cards manually.

Editing or deleting saved autofill information

To change a saved password, go to Settings > Passwords, tap the entry, tap Edit, and change the password. To delete it entirely, tap Edit, then tap the red minus button. For credit cards, go to Settings > Wallet & Apple Pay, tap the card, tap Edit, make your changes, and save.

If you want to remove an address from autofill, open your Contacts app, tap your own contact card (marked "Me" at the top), tap Edit, and delete the address. That address will stop autofilling when ready.

Using iCloud Keychain across devices

When you turn on iCloud Keychain in Settings > [Your Name] > iCloud, your passwords and credit cards sync across all your Apple devices — iPhone, iPad, Mac, and Apple Watch. This means a password you save on your iPhone will autofill on your Mac, and vice versa. If you don't want this sync, turn off iCloud Keychain, but then you'll have to save and manage passwords separately on each device.

If you're signed into iCloud but passwords aren't syncing, check that iCloud Keychain is actually on. Go to Settings > [Your Name] > iCloud and look for Keychain in the list. If it's off, tap it and turn it on. You may be asked to verify with your Apple ID password.

Frequently Asked Questions

Can I autofill passwords without Face ID or Touch ID?

No. iPhone requires biometric verification (Face ID or Touch ID) or your passcode to autofill passwords. This is a security measure to prevent someone else from accessing your passwords if they have your phone. If you don't have Face ID or Touch ID set up, you'll need to enter your passcode instead.

Why is autofill showing suggestions I didn't save?

If you're seeing autofill suggestions for usernames or addresses you don't recognize, they're coming from your Contacts app or from websites that have sent you login hints. Check your Contacts app to see what's saved there. If you see a username suggestion you don't want, you can delete it by tapping the X next to it when it appears.

Does turning off autofill delete my saved passwords?

No. Turning off autofill in Settings just stops iPhone from automatically filling in passwords — it doesn't erase them. Your passwords stay saved in iCloud Keychain. If you turn autofill back on, they'll still be there and ready to use.

Can I autofill passwords in apps, or only in Safari?

Autofill works in both Safari and most third-party apps. When you tap a password field in an app, the autofill keyboard should appear above the regular keyboard. If it doesn't, the app may not support autofill, or you may need to check that app's own settings to enable it.
