How to fix 1Password autofill not working
If 1Password is not autofilling logins, credit cards, or identities, the cause is usually a browser permission, extension issue, app setting, or a sync problem.
This guide walks through the most reliable fixes so you can get 1Password working again across Safari, Chrome, Firefox, Edge, macOS, Windows, iPhone, and Android.
Autofill problems can look similar but have different causes, so the fastest fix depends on where the failure happens.
Start with the basics, then move into platform-specific checks if 1Password still does not fill fields correctly.
Check whether 1Password is unlocked
Autofill will not work if 1Password is locked, signed out, or waiting for reauthentication.
Open the 1Password app or browser extension and confirm your vaults are unlocked before testing a login form.
- Verify that you are signed into the correct 1Password account.
- Check whether the app is locked after a restart or sleep cycle.
- Look for a prompt asking you to approve a sign-in on another device.
If 1Password is unlocked but still not filling, continue to the browser and extension checks.
Confirm that autofill is enabled in 1Password
1Password includes separate settings for filling in browsers, apps, and mobile devices.
If one of those settings is disabled, the app may still open but not insert credentials automatically.
Desktop and browser extension settings
- Open the 1Password app or extension settings.
- Confirm that autofill or browser integration is enabled.
- Make sure the extension has permission to read and change site data.
Some browsers also require you to allow the extension on specific websites.
If you recently changed browser security settings, recheck those permissions.
Mobile autofill settings
- On iPhone and iPad, confirm that 1Password is selected under Password Autofill in iOS settings.
- On Android, verify that 1Password is set as the autofill service.
- Make sure accessibility or overlay permissions are not blocked by battery optimization settings.
Restart the browser, extension, and device
Temporary glitches are a common reason 1Password autofill stops working.
A quick restart clears stale browser sessions, background processes, and extension conflicts.
- Close and reopen the browser.
- Quit the 1Password desktop app and relaunch it.
- Restart the computer or phone if the issue persists.
If the browser extension still fails after restarting, disable and re-enable it once before testing again.
Update 1Password and your browser
Outdated software is a frequent cause of autofill failures, especially after browser updates change extension behavior.
Keep 1Password, your browser, and your operating system current.
- Update the 1Password app to the latest version.
- Update Chrome, Safari, Firefox, or Edge.
- Install any available macOS, Windows, iOS, or Android updates.
Version mismatches can break browser APIs used for form detection, so this step often resolves issues that appear suddenly after an update.
Check browser-specific extension permissions
Modern browsers tightly control password managers and site access.
If 1Password can open but not fill, browser permissions are one of the most likely causes.
Chrome, Edge, and Chromium-based browsers
- Open the extensions page and confirm 1Password is enabled.
- Allow the extension on the current site or set site access to on click or on all sites as needed.
- Disable conflicting built-in password managers if they interfere with detection.
Firefox
- Check that the 1Password extension is active in the add-ons manager.
- Make sure enhanced tracking protection is not blocking the page in unusual ways.
- Reauthorize the extension if Firefox recently cleared permissions.
Safari
- Enable the 1Password extension in Safari settings.
- Approve the extension for private windows if you are testing there.
- Confirm the 1Password app has the proper integration permissions in macOS.
Test on a simple login form
Some websites use custom input fields that make autofill harder to detect.
Before assuming 1Password is broken, test it on a standard login page with familiar username and password fields.
- Try a popular website where you know the saved login exists.
- Click into the username field and look for inline suggestions.
- Use the browser extension button to trigger manual fill.
If 1Password works on some sites but not others, the issue is probably site-specific rather than a global failure.
Use manual fill and save a fresh login
Sometimes 1Password has an outdated entry or the page structure changed.
Manually filling the item and saving a fresh version can restore reliable behavior.
- Open the relevant login in 1Password.
- Copy the username and password into the site manually if needed.
- Save a new password item if the website uses a different login URL or field structure.
For websites with multiple accounts, check that the correct item is being selected from the suggestion list.
Remove conflicts with other password managers
Built-in managers from Google Password Manager, iCloud Keychain, Microsoft Edge, or third-party extensions can interfere with 1Password.
Conflicts may cause duplicate prompts, wrong suggestions, or no autofill at all.
- Disable other browser password managers temporarily.
- Turn off competing extensions such as LastPass, Bitwarden, or Dashlane during testing.
- Check whether your operating system is still offering another default password service.
Once the conflict is removed, test the same login page again to see whether 1Password now appears and fills correctly.
Troubleshoot mobile autofill issues
Mobile autofill can fail for different reasons than desktop autofill.
On iPhone and Android, the app may be installed correctly but not selected as the system autofill provider.
On iPhone and iPad
- Go to Settings, then Passwords, then Password Options or Password Autofill.
- Enable autofill and select 1Password.
- Check that Face ID, Touch ID, or device passcode authentication works.
On Android
- Open system settings and set 1Password as the autofill service.
- Allow 1Password to display over other apps if prompted.
- Exclude 1Password from aggressive battery optimization if it stops appearing.
If autofill works inside the 1Password app but not inside other apps, the target app may not support Android or iOS autofill properly.
Reinstall the extension or app if needed
If basic troubleshooting does not help, a clean reinstall can repair corrupted settings or broken extension state.
This is especially useful after repeated browser crashes or account changes.
- Remove the 1Password browser extension.
- Restart the browser.
- Install the extension again from the official store.
On desktop or mobile, uninstalling and reinstalling the app may clear local configuration problems.
Make sure you know your account details before removing the app.
When to contact 1Password support
If 1Password autofill still does not work after checking unlock status, permissions, updates, and conflicts, the issue may be tied to your device, account, or a specific website implementation.
Support can help review logs, identify browser incompatibilities, and confirm whether the problem is known.
- Collect the browser version and 1Password version.
- Note whether the problem happens on one site or everywhere.
- Describe whether manual fill, inline suggestions, or extension button fill is failing.
The more specific your report, the faster support can isolate the cause and recommend the right fix.
