The most consistent cause is the “Integrate with 1Password app” option being turned off in either the app or extension settings. Other reasons include corrupted extension files, Chrome updates, or native messaging being blocked by security tools
1. Restart Chrome
Before proceeding with the solutions, restart the Chrome browser after ensuring that no Chrome or 1Password processes are running in your system’s Task Manager. This simple action can resolve temporary glitches. Additionally, restart your computer after completely exiting the 1Password application. Ensure that your license or subscription is currently valid. Also, verify that your antivirus or firewall is not interfering with the 1Password extension. If available, try to enable the Native Messaging Protocol via Help < Advanced in 1Password, as this can resolve integration issues.
2. Update the 1Password Extension/Application to the Latest Version
Frequent updates to the 1Password extension and application introduce new features, enhance compatibility, and address known bugs. If you are running an outdated version, compatibility problems can arise. In this scenario, updating both the 1Password extension and application should resolve the issue.
3. Update the Chrome Browser to the Latest Version
Chrome is regularly updated to improve security, performance, and extension compatibility. An outdated browser can lead to extension failures due to mismatched versions. Keeping Chrome current can prevent compatibility issues with 1Password.
4. Use Only One Version of 1Password Applications or Extensions
Running multiple versions of 1Password—such as 1Password X and the traditional extension—or having both the web and desktop versions installed can cause conflicts. Keeping only one version installed enhances stability and compatibility.
5. Reinstall the 1Password Extension
Corrupted or incomplete extension installations can prevent 1Password from functioning. Reinstalling the extension can repair such corruption and restore normal operation.
6. Enable the 1Password Extension Helper
The 1Password extension relies on the extension helper to synchronize properly. If disabled, synchronization may break. Activating this helper ensures optimal integration, especially on macOS.
7. Re-Run the 1Password Application Setup
The 1Password companion app must be properly configured for the Chrome extension to function, especially for non-cloud versions. Incorrect registry entries can block integration. Running the setup process again helps fix these issues on Windows.
8. Reinstall the 1Password Application
Moving the installation folder or file corruption can break the companion app, causing the extension to fail. Reinstalling ensures you have clean, intact files. Mac users can try the 1Password Troubleshooting Utility first.
9. Disable ‘Verify Web Browser Code Signature’ in the 1Password Application Settings
Older versions of 1Password (e.g., version 4) may encounter compatibility problems with modern browsers. Disabling verification of the web browser code signature can sometimes help, though it does introduce a security risk. Warning: Disabling this check may expose your system and data to attacks. Proceed only if necessary and understand the risks.
10. Remove All Extensions from Chrome
Other browser extensions can interfere with 1Password’s operation. Removing all extensions eliminates conflicts and helps identify the problematic one.
11. Reinstall the Chrome Browser
A corrupt Chrome installation can prevent extensions from working correctly, even if other troubleshooting measures fail. Reinstalling Chrome will refresh its files and settings, resolving persistent issues. If the problem continues, try reverting to an older version of the 1Password application. On a Mac, move both Chrome and the 1Password app to the System Applications folder. Additionally, try logging out of the Mac App Store and iTunes Store, restarting your device, and then logging back in. This can resolve credential-related problems. As an additional step, make sure the option Never Display in Browser is unchecked in the 1Password application settings. If none of these solutions work, consider switching to the 1Password X extension (after uninstalling the current 1Password application and extension).
