Autofill data

Autofill data is the information a browser saves to fill forms for you — addresses, names, payment cards, and saved passwords. It uses almost no space; clearing it is a privacy and convenience choice, since the browser will stop suggesting those entries.

Autofill data

Also known as: autofill, saved form data, saved passwords and addresses

Autofill data is the information a browser saves to fill forms for you — addresses, names, payment cards, and saved passwords. It uses almost no space; clearing it is a privacy and convenience choice, since the browser will stop suggesting those entries.

  • Saved addresses, cards, and passwords for forms
  • Uses negligible space — a privacy choice
  • Passwords and cards are stored encrypted

What autofill remembers

As you fill in forms, the browser offers to remember entries so it can complete them later: contact and shipping details, card numbers, and login credentials. Passwords and cards are stored encrypted, often synced through your account, and are kept separate from ordinary form text.

This data is tiny in storage terms — it is a convenience and security feature, not a space hog. Clearing it does not meaningfully free a full disk.

Managing and clearing it

In Chrome, autofill lives under Settings > Autofill and passwords, where you can edit or remove addresses, payment methods, and saved passwords individually. To wipe form text in bulk, use Delete browsing data > Autofill form data.

On iOS, Safari uses the system Settings > Passwords and Settings > Safari > AutoFill for contact and card info. Clearing autofill means re-entering those details next time, but never affects your cache or sign-in cookies.
