Your Free Guide to Turning Off Autofill Settings

Understanding Autofill: What It Is and How It Works

Autofill is a feature found on most devices and web browsers that automatically fills in information you've entered before. When you type your name, address, email, phone number, or payment information into a form, your browser or device remembers it. The next time a website asks for that same information, autofill suggests completing the field without you typing it again.

This feature exists across multiple platforms. On your computer, web browsers like Chrome, Firefox, Safari, and Edge all have autofill capabilities. On smartphones and tablets, iOS and Android devices store autofill data. Password managers and credit card companies also offer autofill services. According to a 2023 survey by Pew Research, approximately 64% of internet users have autofill enabled on at least one device.

Autofill works by storing data in your browser's or device's memory. When you visit a website with form fields, the system compares what's on the page with information it has saved. If there's a match—like a field labeled "email address"—it offers to fill it in. You can typically accept the suggestion by pressing Enter or clicking on it, or you can ignore it and type manually.

Different types of autofill include contact information (name, address, phone number), login credentials (usernames and passwords), payment information (credit card numbers and expiration dates), and personal details (date of birth, social security number). Each type serves a different purpose and can be managed separately.

Practical Takeaway: Before learning to turn off autofill, understand what information yours is storing. This helps you decide whether you want to disable it entirely, delete stored data, or keep it but manage it more carefully. Check what your browser has saved by looking in settings—most store far more information than users realize.

Why You Might Want to Disable Autofill

People choose to turn off autofill for several reasons related to privacy, security, and personal preference. Understanding why you might want to disable it helps you make an informed decision about your own settings.

Security concerns are a primary reason. When autofill stores sensitive information like credit card numbers or passwords, that data sits on your device. If someone gains physical access to your computer or phone, they could potentially access stored payment information. Additionally, if your device is compromised by malware, autofill data could be targeted. The FBI reported in 2022 that credential theft increased by 74% year-over-year, making password storage a legitimate security worry for many users.

Privacy is another consideration. Autofill creates a digital trail of personal information on your device. If you share your computer with family members or colleagues, they might see your stored information when using forms. Additionally, some websites may access autofill data in ways you don't realize or intend, potentially tracking your behavior across multiple sites.

Accuracy problems occur when autofill stores outdated information. If you moved and didn't update your address, autofill will continue suggesting the old one. Similarly, if a form field is mislabeled or confusing, autofill might fill it with incorrect information—like putting your work address in a field meant for your home address.

Some users simply prefer manual entry for important information. This creates a moment of deliberate attention when filling in sensitive details, which some people find reassuring. There's also the practical issue that autofill isn't always helpful—it might suggest information that's close but not quite right, requiring correction anyway.

Practical Takeaway: List your specific concerns before disabling autofill. Are you worried about shared devices, outdated information, or general security? Your primary concern determines which settings to adjust. You might not need to disable everything—sometimes selective management works better.

Turning Off Autofill in Chrome

Google Chrome is the most widely used web browser, with over 63% of the global browser market share according to StatCounter data from 2024. If you use Chrome, you can disable autofill through its settings menu.

To access autofill settings in Chrome on a desktop computer, open Chrome and click the three vertical dots in the upper right corner. Select "Settings" from the dropdown menu. On the left side, click "Autofill and passwords." This section contains all autofill-related options.

In the Autofill and passwords section, you'll see several toggles. "Autofill addresses and more" controls whether Chrome suggests contact information. "Autofill payment methods" controls whether it suggests credit card information. "Passwords" controls password autofill. You can turn each one on or off independently. To completely disable autofill, turn all three toggles to the "off" position.

If you want to keep autofill on but delete previously saved information, use the same Autofill and passwords section. Click "Addresses and more," and you'll see a list of saved contact information. Hover over each entry and click the trash icon to delete it. Do the same for payment methods by clicking "Payment methods" and deleting each saved card.

On a smartphone or tablet using Chrome, the process is similar but slightly different. Open Chrome and tap the three dots in the lower right corner (on iOS) or upper right corner (on Android). Tap "Settings," then "Autofill and passwords," and turn off whichever options you prefer.

For users who want to keep autofill but limit it, Chrome offers a middle ground. You can turn on autofill but not save new information by adjusting settings. Turn off "Save and fill payment methods" while keeping the autofill toggle on—this way, previously saved information still works, but Chrome won't add new payment details.

Practical Takeaway: Write down which autofill features you're disabling before you start. Chrome allows selective control—you might want to keep address autofill but disable payment information autofill, for example. This approach provides security without completely sacrificing convenience.

Turning Off Autofill in Firefox, Safari, and Edge

While Chrome dominates browser usage, Firefox, Safari, and Microsoft Edge serve millions of users. Each has its own autofill settings, though the general concepts are similar.

Firefox: Open Firefox and click the three horizontal lines (menu button) in the upper right corner. Select "Settings." Click "Privacy & Security" on the left side. Scroll down to the "Forms & Autofill" section. You'll see checkboxes for "Autofill addresses" and "Autofill credit cards." Uncheck both to disable autofill. To delete previously saved information, click "Manage addresses" or "Manage credit cards" and remove entries by clicking the trash icon next to each one.

Safari: On Mac computers, click "Safari" in the top menu bar and select "Settings." Click the "Autofill" tab. Uncheck any boxes next to "Using information from my contacts," "Credit cards," "Usernames and passwords," or any other options you want to disable. On iPhone or iPad, open Settings (not Safari), scroll to Safari, and tap "Autofill." Toggle off "Autofill Credit Cards," "Autofill Contact Info," and "Autofill Passwords."

Microsoft Edge: Open Edge and click the three dots in the upper right corner. Select "Settings." Click "Privacy, search, and services" on the left. Scroll to "Clear browsing data" and click "Choose what to clear." To disable autofill going forward, go back to Settings and click "Autofill." Turn off "Save and fill basic info," "Save and fill passwords," and "Save and fill payment info."

Each browser allows you to delete stored autofill data separately from disabling the feature. If you want to keep autofill active but remove old information, most browsers provide a "Manage" option where you can review and delete individual entries without fully disabling the feature.

One important note: these browser settings only control autofill within that specific browser. If you use multiple browsers, you'll need to adjust settings in each one. Additionally, websites may have their own autofill features independent of your browser, which may require separate adjustment.

Practical Takeaway: If you use multiple browsers, create a simple checklist and work through each one systematically. The steps are similar enough
