Learn How to Manage Your Device Autofill Settings

Understanding Autofill: What It Is and How It Works

Autofill is a feature found on most modern devices that automatically completes information you've typed before. When you start typing something—like your email address, phone number, or a password—your device remembers it and suggests filling in the rest. This happens on smartphones, tablets, computers, and web browsers. The purpose is to save you time by reducing how much you need to type repeatedly.

Your device stores this information locally, meaning it stays on your device rather than being sent to a company's server (though this varies by settings). When autofill is active, your device scans what you're typing and matches it against saved information. If there's a match, it offers to complete the field for you. You can accept the suggestion by tapping or clicking it, or ignore it and keep typing.

Different devices handle autofill differently. On iPhones and iPads, Apple's system uses iCloud Keychain to store passwords and payment information. On Android devices, Google's autofill service works similarly. Windows computers have their own autofill systems, as do Mac computers. Web browsers like Chrome, Firefox, Safari, and Edge each have their own autofill mechanisms.

Autofill typically covers several types of information: passwords, usernames, email addresses, phone numbers, home and work addresses, credit card numbers, and answers to security questions. Some systems also remember preferences like your preferred shipping method or billing address.

Practical Takeaway: Before you begin managing autofill settings, understand that autofill is designed as a convenience feature, not a security measure. Knowing what your device stores and how it stores it helps you make informed decisions about whether to use it and how much to rely on it.

Accessing Autofill Settings on Different Devices

The location of autofill settings varies depending on what device you use. On an iPhone or iPad, you'll find autofill settings within the Settings app. Open Settings, then scroll down and tap "Passwords" (on newer iOS versions) or "Accounts & Passwords." From there, you can manage which apps and websites can use your saved passwords and payment information. You may also see a section for AutoFill, which lets you choose whether to use passwords, payment methods, and contact information for filling forms.

On Android devices, the process differs slightly. Open your Settings app and look for "Google" or "Autofill" options. If you see a Google section, tap it and then look for "Manage your Google Account." From there, go to the "Security" tab, scroll down to "Your devices," and find autofill settings. Alternatively, you can go directly to Settings and search for "autofill" to find the relevant options. Many Android devices also store autofill information through Samsung Pass or similar manufacturer-specific apps.

On Windows computers, open Settings and navigate to "Accounts," then "Sign-in options." Scroll down to find "Autofill" or password-related settings. You can also access autofill through the browser you use. In Google Chrome, click the three vertical dots in the upper right, select "Settings," then go to "Autofill" to see what Chrome has stored. In Microsoft Edge, click the three dots, select "Settings," then "Privacy, search, and services," and scroll to find autofill options.

Mac users can find autofill settings in System Preferences (or System Settings on newer versions). Look for "Passwords" or "Autofill" under the Security & Privacy section. For Safari specifically, go to Safari menu, then "Preferences," and click the "Autofill" tab.

Practical Takeaway: Write down the steps for accessing autofill settings on each device you own. Keep these instructions in a safe place so you can return to these settings whenever you want to review or change them.

Deciding What Information to Allow Autofill to Store

Before you turn on autofill features or add information to them, it helps to think about what you're comfortable storing. This is a personal decision based on how you use your device and who might access it. Some people feel comfortable storing passwords because they use strong encryption and their device stays private. Others prefer not to store passwords at all, believing that entering them manually adds a layer of protection.

Payment information is another area where comfort levels vary. Storing credit card numbers means you don't have to type them out every time you make an online purchase, but it also means that anyone who gains access to your device could potentially use your card. Consider whether you share your device with others, whether you use it in public places, or whether you ever leave it unattended.

Contact information like your name, address, phone number, and email are generally lower risk to store since this information is often publicly available anyway. However, you might want to limit this if you're concerned about privacy. Security questions and answers are trickier—storing answers to "What is your mother's maiden name?" or "What was the name of your first pet?" could be risky if someone gains access to your device, since these answers are often used to verify your identity in password recovery scenarios.

Think about the following questions: Who has physical access to this device? How often do I need to enter this type of information? What would happen if someone else accessed this information? Am I comfortable with a particular app or website storing this data? Your answers will guide what you should allow autofill to store. You don't have to make a permanent decision—autofill settings can be changed at any time, and you can delete stored information whenever you want.

Practical Takeaway: Create a personal autofill policy for each device you own. Write down what types of information you're willing to have autofilled and what you want to keep off these systems. Review this policy once every few months to see if your comfort level has changed.

Managing Passwords and Login Information in Autofill

Passwords are often the most sensitive information stored in autofill systems. When you enable password autofill, your device stores login credentials and offers to fill them in when you revisit websites or apps. This is convenient but requires careful management. Start by reviewing what passwords your device has already saved. In most cases, you can see a list of saved passwords (though you may need to verify your identity first by entering your device password or using biometric authentication).

Look through this list and ask yourself: Do I still use all these accounts? Are there passwords here I don't recognize? For old accounts you no longer use, you have two options: delete them from autofill storage, or better yet, go to those websites and change or delete your passwords. This prevents someone from using old, forgotten passwords to access abandoned accounts.

When you create new accounts or change existing passwords, your device usually asks whether you want to save the new password. You can choose to save it, skip saving it, or update an existing saved password. If you're using a strong password manager (a separate app designed specifically for storing passwords), you might want to skip saving passwords in your device's autofill system and use the password manager instead. This gives you more control and often provides additional features.

For important accounts—especially banking, email, or social media—consider not saving the password in autofill. These accounts are often targeted by hackers, and manually entering the password each time adds an extra layer of security. For less sensitive accounts, like websites where you shop or read articles, autofill is less risky. You can also update your autofill settings so that your device asks you to confirm before filling in a password, rather than doing it automatically.

Practical Takeaway: Do a password audit on each device. Delete autofilled passwords for accounts you no longer use, and consider removing passwords for accounts you consider high-priority and sensitive. This reduces the amount of valuable information stored on your device.

Controlling Autofill Permissions for Apps and Websites

Autofill doesn't work uniformly across every app and website—you can control which ones are allowed to use your stored information. On iPhones and iPads, go to Settings > Passwords, and you'll see a list of apps that have requested autofill access. You can toggle these on or off individually. Some apps might ask permission the first time they need to autofill information; you can allow or deny each request as it comes up.

On Android, the process is similar but varies by device manufacturer. Generally, you can go to Settings > Apps and look
