About the message
For your protection, 1Password verifies the identity of your browser before filling your information, like passwords, credit cards, or addresses. This feature prevents your data from being stolen in case your browser has been tampered with.
What you should do
Seeing this message does not always indicate a security problem. The solution may depend on which browser you are using.
Chrome, Firefox, or Opera: Restart your browser
1Password can’t verify the identity of your browser if it’s in the middle of an update. Quit your browser and restart it. Doing so will allow the update to complete, and the signature will once again be valid.
Chromium: Use a browser that has been signed
The Chromium team has no plans to begin signing Chromium. That means 1Password has no way of knowing if your Chromium installation is safe. Switch to a browser that has been signed, like Chrome, Safari, Firefox, or Opera.
Beta versions of Safari, Chrome, and Opera: Use the 1Password beta
If you use a beta version of a major browser, like Safari Technology Preview or Opera Developer, use the latest beta version of 1Password.
If you still see this message
If none of the above suggestions helped, try the steps below.
Place browsers in the Applications folder
1Password for Mac can only reliably verify the signature of your browser if it is in the Applications folder. If your browser is in a subfolder or somewhere else on your Mac, move it to the Applications folder.
Restart your computer
Restart your computer before going further. It’s a simple step with no downside.
