“Unknown is connected, but its code signature could not be verified” is an annoying 1Password error that Chrome users may sometimes encounter when logging in to a new webpage. The error message indicates 1Password failed to verify Chrome’s code signature. Most likely, this is because a newer browser version is available, and there’s a minor compatibility glitch between your password manager and your browser. Let’s see how you can fix it.
How to Fix 1Password Code Signature Errors on Chrome
Update Your OS, Browser, and 1Password Version
First and foremost, make sure all your apps are up-to-date, and don’t forget to update your OS version as well. If you recently updated Chrome, check if there’s a newer 1Password version available and install it on your computer. Most likely, 1Password’s developers already updated the extension to make it compatible with the latest Chrome release.
To update Chrome, click on the browser menu, go to Help, select About Chrome and check for updates.
To update 1Password, click on Chrome’s menu, go to More tools and then select Extensions. Locate 1Password, click on the Details button, and hit the Update button (if there is one). To check when the devs last updated the extension, go to 1Password’s Chrome Web Store page, and scroll down to Additional Information.
If you want to update your Windows 10 computer, go to Settings → Update, and Security → Windows Update → Check for updates. But if you run Chrome on Mac, go to System Preferences → System Update → Check for updates.
Clear Your Browser Cache and Disable Your Extensions
Your cache and the other extensions you added to Chrome might be interfering with 1Password. Clear the cache, disable all the extensions except 1Password and check the results.
- Click on Chrome’s menu, and select History twice.
- Click Clear browsing data (left pane).
- Select the time range and check the cookies and cache checkboxes.
- Hit the Clear data button and restart Chrome.
Check if you’re still getting the same error. If this is the case, disable all your browser extensions but keep 1Password. Click on Chrome’s menu, select More tools, go to Extensions and manually toggle off the extensions.
Uninstall Chrome Beta
If you’re using Chrome Beta, exit the channel and install the newest stable browser release. Chrome Beta is still a work in progress, and some features may not be compatible with 1Password. Or maybe the code is not that well-optimized yet. So, uninstall Chrome Beta, restart your computer, install a stable Chrome version and check the results.
Disable Your Security and Privacy Apps
Your security and privacy programs may sometimes interfere with 1Password. The quickest way to test that hypothesis is to disable these tools and check if 1Password can verify the code signature. If this is the case, go to your antivirus and firewall settings and whitelist 1Password.
Move Chrome in the Applications Folder
If you’re on Mac, make sure Chrome is in the Applications folder otherwise, 1Password won’t be able to verify the signature of your browser reliably. If Chrome’s installation folder is somewhere else on your computer, move it to Applications. Restart your Mac, launch Chrome, and check if 1Password is working properly.
⇒ Note: Some users said that disabling the “Verify web browser code signature” option in 1Password fixed the error. Go to Help, select Advanced and then turn off this option. However, we’d strongly vote against disabling such an important security feature for obvious reasons.
If 1Password fails to verify Chrome’s code signature, ensure you’re running the latest Chrome, 1Password, and OS versions on your computer. Additionally, clear your browser cache and disable all your browser extensions, except 1Password. If you use Chrome Beta, uninstall this browser version and install a stable release.
