How to Use Autofill on Android Oreo

Android Oreo (8.0 and 8.1) introduced a system-level Autofill framework that lets apps like password managers and form fillers securely populate usernames, passwords, addresses, and other repeated information. This guide walks you through enabling Autofill, choosing a service, and using it in apps, plus fixes for common problems.

What You’ll Need

An Android device running Oreo (8.0 or 8.1). To check: go to Settings > System > About phone and look at the Android version.
An Autofill service installed. This can be a dedicated password manager (like LastPass, 1Password, or Bitwarden) or a browser with Autofill support (like Chrome). If you don’t have one, you can use Google’s built-in Autofill with Chrome as the source.
If you plan to use a third-party app, install it from the Google Play Store and sign in to your account.

Step-by-Step

Open Settings. Swipe down from the top of the screen and tap the gear icon, or find the Settings app in your app drawer.
Go to System > Languages & input > Advanced. The exact path is: Settings > System > Languages & input > Advanced. On some devices, it may be under Settings > System > Language & input or Settings > General management.
Tap “Autofill service.” You’ll see a list of available services. If you haven’t set one up, it may say “None” or “Google.”
Select your preferred Autofill service. Tap the radio button next to the service you want to use (e.g., “Google” or your password manager). If you don’t see your app, make sure it’s installed and updated.
Confirm the selection. A dialog will appear explaining what the service can see. Tap OK to allow it to read your screen and fill in forms.
Set up the service itself. Open the Autofill app (e.g., your password manager) and follow its setup wizard. This usually involves creating a master password, enabling accessibility (for some apps), and allowing the app to save new credentials when you log in.
Test it in a real app. Open an app or website where you have an account. Tap on a username or password field. You should see a dropdown or a suggestion bubble appear above the keyboard. Tap the suggestion to fill in the saved information.
Save new credentials. When you log into a new site or app, a prompt will appear asking if you want to save the username and password. Tap Save (or Update if it’s a change).

Common Mistakes

Not enabling the service after installing. Installing a password manager doesn’t automatically make it the Autofill service. You must select it in Settings as shown above.
Choosing “None” accidentally. Some devices default to “None” until you pick a service. If Autofill doesn’t work, check that a service is selected.
Using a service that doesn’t support Oreo’s Autofill. Older versions of some apps may not have updated to support the API. Make sure your app is updated to the latest version.
Ignoring the “Save” prompt. If you dismiss the save prompt, the credential won’t be saved, and you’ll have to type it manually next time.
Confusing Autofill with the keyboard’s own autocomplete. The system Autofill is separate from your keyboard’s word suggestions. Make sure you’re looking for the Autofill dropdown, not the keyboard’s prediction bar.

Tips

Use a dedicated password manager for better security. Google’s built-in Autofill works, but a password manager offers encrypted storage and cross-device sync.
Set a screen lock. Since Autofill can fill in sensitive data, it’s wise to have a PIN, pattern, or fingerprint lock on your device.
If you have multiple accounts for the same site, tap the dropdown arrow on the suggestion to see all saved accounts and choose the right one.
To remove a saved entry, go to the Autofill service’s settings (e.g., in your password manager) and delete it there. You can also clear all Autofill data from Settings > System > Languages & input > Advanced > Autofill service by tapping the gear icon next to the service (if available).
On some Samsung devices, the path may be Settings > Biometrics and security > Autofill service. If you can’t find it, use the search bar in Settings and type “Autofill.”

Troubleshooting

Autofill doesn’t appear at all. First, confirm the service is selected in Settings. If it is, try restarting your device. Also, check that the app you’re trying to fill in is not an older app that doesn’t support the Autofill API—some apps (especially games or banking apps) may disable it for security reasons.

Suggestions show but are wrong or outdated. Go to your Autofill service’s settings and edit the saved credentials. If you’ve changed your password, update the saved entry. You can also delete the entry and save it again next time you log in.

Autofill works but doesn’t fill all fields. Some apps have custom fields that the Autofill service can’t recognize. Try using the “Autofill” option from the overflow menu (three dots) if available, or manually tap each field and select the suggestion.

Autofill service keeps stopping or crashing. Clear the app’s cache and data (Settings > Apps > [App name] > Storage > Clear cache). If that doesn’t help, uninstall and reinstall the app, then set it up again.

After a system update, Autofill stops working. Sometimes updates reset the Autofill service to “None.” Go back to Settings and reselect your service.

Google Autofill doesn’t save new passwords. Make sure you’re signed in to your Google account on the device and that Chrome is set as the source in Google Autofill settings (inside the Autofill service settings).

Frequently Asked Questions

Q: Does Android Oreo Autofill work in all apps?
No. Apps must opt in to support the Autofill framework. Most modern apps do, but some older or highly secure apps (like banking) may not. If you don’t see suggestions, the app may not support it.

Q: Is Autofill safe to use?
Yes, the system uses a secure connection between the service and the app. However, you should only use trusted Autofill services from reputable developers, and keep your device locked.

Q: Can I use multiple Autofill services at once?
No. Android only allows one Autofill service to be active at a time. You can switch between them, but only one will work at a time.

Q: How do I disable Autofill?
Go to Settings > System > Languages & input > Advanced > Autofill service and select “None.” This will turn off Autofill entirely.

Q: Will Autofill work in Chrome and other browsers?
Yes, if the browser supports the Autofill API. Chrome does, and most other major browsers do too. If not, the browser may have its own built-in password manager that you can use instead.

Q: My password manager app is not showing in the Autofill service list. What should I do?
Make sure the app is installed and updated. If it still doesn’t appear, the app may not support Android Oreo’s Autofill framework. Contact the app developer for support.
